72c4a0ed04 fix: prevent silent auth error swallowing in fetch error utility
- Add setAuthErrorHandler() registration mechanism to utils/fetchError.ts
- Implement fallback logging when auth errors (401/403) occur without registered handler
- Update AuthProvider to register both API client and fetch error handlers
- Ensure auth errors are handled deterministically at multiple layers
- Add comprehensive tests for auth error handler registration and fallback logging
- Update Web-Development.md documentation with auth error handling contract

Fixes issue #21: Silent auth errors are now caught and logged if the handler is not
registered, preventing actionable errors from being silently swallowed.

ca23858946 Add skeleton loading components for progressive UX
Implement standardized skeleton loading placeholders to reduce perceived
loading time and prevent layout shift during data fetches. These components
match actual content dimensions exactly, improving perceived responsiveness.

New skeleton components in src/components/skeletons/:
- SkeletonTable: Table/grid loading with customizable rows and cells
- SkeletonTableRow: Individual animated skeleton row
- SkeletonChart: Chart/graph loading with bars matching dimensions
- SkeletonStat: Stat card loading with label and value
- SkeletonFormField: Form input loading placeholder
- PageLoadingSkeleton: Convenience wrapper for page-level loading states

Implementation details:
- All skeletons use global 'skeleton-pulse' animation (2s cycle)
- Dimensions match real content to prevent layout shift on arrival
- Marked with aria-hidden and role=presentation for accessibility
- Theme-aware colors using Fluent UI tokens
- Respects prefers-reduced-motion setting

Updates:
- ChartStateWrapper: Uses SkeletonChart instead of spinner
- PageFeedback: Added PageLoadingSkeleton component
- App.tsx: Injects skeleton styles at startup
- Web-Design.md: Added § 8a with loading UX guidance and usage examples

All components tested (22 tests, 100% passing) and linted.

2fea513c9c docs: make provider dependency chain explicit with documentation and tests
This addresses issue #19 by making the implicit provider dependency order
explicit and order-sensitive.

Changes:
1. Created PROVIDER_ORDER.md - comprehensive documentation explaining:
   - The provider hierarchy from outermost to innermost
   - Why each provider must be at its position
   - Order-sensitive pitfalls and what would break
   - Guidelines for adding new providers in the future

2. Added provider composition tests (providerComposition.test.tsx):
   - 13 comprehensive tests validating provider order and dependencies
   - Tests verify all providers mount correctly
   - Tests check that hooks only work inside correct providers
   - Tests validate async initialization (AuthProvider, TimezoneProvider)
   - Tests verify theme persistence and notification propagation

3. Updated App.tsx with inline documentation:
   - Added detailed provider order contract in JSDoc header
   - Inline comments explaining each provider's position
   - Reference to PROVIDER_ORDER.md for detailed rationale

4. Updated Web-Development.md:
   - Added new section 5.5 'Provider Order Contract'
   - Documents provider hierarchy and rationale
   - Links to comprehensive provider documentation
   - References regression test suite

All tests pass. TypeScript compilation succeeds. Build succeeds.
The provider order is now explicit and future refactors can validate
compliance through the regression test suite.

d10145e5d6 refactor(frontend): extract shared fetch lifecycle into useFetchData base hook
Eliminates ~100 lines of duplicated code across useListData and usePolledData
by creating a composable base hook that handles:
- Abort controller lifecycle and cancellation
- Loading/error state management
- Fetch error handling
- Unmount cleanup

Changes:
- Create hooks/useFetchData.ts with base fetch lifecycle (no effects on consumers)
- Refactor useListData to compose useFetchData, returns items array by default
- Refactor usePolledData to compose useFetchData, adds polling and focus-refetch
- Add comprehensive tests for useFetchData base hook
- Document hook architecture and composition pattern in Web-Development.md

Result: Both hooks now use shared primitives, reducing maintenance burden
and ensuring consistent cancellation/error handling across all data fetches.

5166789b68 feat: Implement typed error contracts in generic hooks
Introduce discriminated FetchError union type to replace weak string error
handling in API calls and hooks. Enables actionable error diagnostics.

Changes:
- Create types/api.ts with FetchError discriminated union (api_error,
  network_error, abort_error)
- Export type guards: isAuthError, isAbortError, isNetworkError, isApiError
- Update useListData and usePolledData to expose typed FetchError instead of
  string
- Add getErrorMessage() helper to extract displayable messages from FetchError
- Add createStringErrorAdapter() for backward compatibility with string error
  state
- Update handleFetchError() to work with both FetchError and string setters
- Update all consumer hooks to expose typed errors
- Update components to use getErrorMessage() when displaying errors
- Update tests to mock FetchError instead of strings
- Add comprehensive typed error model documentation to Web-Development.md

This enables better error handling patterns:
- Check error.type to distinguish between API, network, and abort errors
- Extract status codes for specific handling (401/403 auth, 50x server errors)
- Maintain backward compatibility with existing string-based error states

All TypeScript compilation passes with no errors.

6c8e2b3423 fix(#16): Establish consistent API usage layering patterns
- Refactor useActiveBans to use useListData generic hook instead of inline state management
- Refactor useBans to use useListData generic hook for consistency
- Add comprehensive 'API Usage Layering' section to Web-Development.md documenting:
  - Tier 1: API Functions (pure wrappers around HTTP calls)
  - Tier 2: Reusable Generic Hooks (useListData, useConfigItem for common patterns)
  - Tier 3: Domain Hooks (compose Tier 2 with domain-specific logic)
  - Tier 4: Components (receive data/actions via props or context)
- Document pattern for action callbacks with automatic data refresh
- List anti-patterns to avoid for future consistency

These changes improve composability, testability, and reduce code duplication by
establishing a clear convention for data-fetching patterns across the frontend.

da6433b2cf Improve error boundary granularity with page and section level boundaries
Implement three-level error boundary strategy:
- Top-level (app shell): catches critical failures
- Page-level: preserves navigation when page crashes
- Section-level: graceful degradation for charts/tables

Create new components:
- PageErrorBoundary: wraps page routes
- SectionErrorBoundary: wraps data-heavy sections

Enhance ErrorBoundary with customizable titles, messages, and reload behavior.

Apply page boundaries to all route handlers in App.tsx.

Apply section boundaries to:
- DashboardPage: server status, ban trend, country charts, ban list
- JailsPage: jail overview, ban/unban form, IP lookup
- MapPage: world map, ban table
- ConfigPage: configuration editor
- HistoryPage: history table, IP detail view
- BlocklistsPage: sources, schedule, import log

Update Web-Development.md with error boundary strategy documentation.

42beb9cf3b refactor: Decompose ConfigPage into focused routing and component layers
Split the over-centralized ConfigPage into focused, composable layers:

1. useTabRouter hook: Encapsulates tab state management and URL synchronization
   - Maintains selected tab and active item (e.g., jail name)
   - Syncs state to location.state for deep linking and browser history
   - Supports bookmarkable URLs and back/forward navigation

2. ConfigPageContainer: Orchestrates tab navigation
   - Manages TabList and routes tab selection events
   - Conditionally renders tab content panels
   - Delegates domain-specific logic to tab components

3. ConfigPage: Focused page layout component
   - Renders page structure (header, title, description)
   - Delegates tab orchestration to ConfigPageContainer
   - No routing or tab state logic

Benefits:
- Page is now 30 lines vs 125 lines (76% reduction)
- Tab state management is reusable for other multi-tab pages
- Each tab component remains focused on domain-specific UI
- Deep linking and browser history work out of the box
- Easier to test and maintain

Added comprehensive tests:
- useTabRouter: 6 tests covering state initialization, tab selection, and deep linking
- ConfigPageContainer: 8 tests covering tab rendering and navigation
- ConfigPage: 3 tests for page structure

Updated Web-Development.md with tab orchestration pattern documentation.

69a5f0ceb1 refactor: eliminate prop drilling in JailsPage with context provider
Replace multi-hop prop forwarding with a dedicated JailContext that manages
jail state and actions. This reduces coupling, simplifies the component hierarchy,
and makes the data flow more explicit.

Changes:
- Create JailContext.tsx with JailProvider and useJailContext hook
- Wrap JailsPage content with JailProvider to expose jail state
- Refactor JailOverviewSection to use useJailContext instead of props
- Remove 10 props from JailOverviewSection component signature
- Add comprehensive documentation on state ownership and prop drilling

Benefits:
- Eliminates unnecessary prop chains through intermediate components
- Makes component contracts clearer (no longer need to pass unrelated props)
- Simplifies future refactoring of jail-related functionality
- Sets a pattern for other page-scoped state management

Testing:
- TypeScript type check passes (tsc --noEmit)
- Frontend builds successfully
- Existing JailsPage tests pass with new context structure

93021500c3 TASK-033: Remove session token from JSON response body
Fixes a critical security vulnerability where the session token was
being returned in the JSON response body of POST /api/auth/login.
This exposed the token to JavaScript, allowing malicious scripts to
steal it and bypass the HttpOnly cookie protection.

Changes:
- Backend: Remove 'token' field from LoginResponse model (auth.py)
- Backend: Update login() endpoint to return only 'expires_at'
- Frontend: Update LoginResponse type to exclude 'token' field
- Backend: Update test helper _login() to extract token from cookie
- Backend: Update test cases to verify token is NOT in response body
- Documentation: Add section 'Authentication Endpoints' in Backend-Development.md
- Documentation: Update Web-Development.md to explain HttpOnly cookie benefits

Security benefit: Session tokens are now only accessible via HttpOnly
cookies, protected from JavaScript access, XSS attacks, and malicious
third-party scripts. The frontend continues to use only the cookie for
authentication.

All auth tests pass (23 tests). Type checking and linting pass with
zero errors.

3095fa3313 fix(frontend): deduplicate setup status API calls using shared hook
Implement request deduplication to prevent multiple duplicate calls to GET
/api/setup when multiple components mount simultaneously. The fix introduces:

1. New 'useSharedSetupStatus' hook with module-level caching
   - Shares a single in-flight request across all consumers
   - Implements 30-second cache TTL with cache invalidation
   - Notifies all subscribers when cache is invalidated

2. Refactored 'useSetup' hook to use shared cache
   - Internally uses useSharedSetupStatus for status checks
   - Calls invalidateSetupStatus() after successful setup submission
   - Maintains backward-compatible API

3. Updated components using setup status
   - SetupGuard and SetupPage automatically benefit from deduplication
   - No changes needed to consumer code

4. Updated tests
   - Mocked useSharedSetupStatus in component tests
   - Added comprehensive tests for cache behavior
   - All existing tests pass

5. Documentation updates
   - Added 'Request Deduplication & Shared Caching' section to Web-Development.md
   - Explains when and how to use shared hooks
   - Provides complete implementation example

This eliminates wasted resources from duplicate API calls and potential
race conditions where different requests return slightly different states.

29daaa9906 TASK-004: Bootstrap frontend auth state from backend session check
Validates session on app mount by calling GET /api/auth/session instead of relying
solely on cached sessionStorage. This ensures the UI state always reflects server
reality — expired or revoked sessions are detected immediately.

Changes:
- Backend: Add GET /api/auth/session endpoint (requires valid session, returns 200/401)
- Frontend: Add useSessionValidation hook for mount-time validation
- Frontend: Add SessionValidationLoading component for validation spinner
- Frontend: Update AuthProvider to call validation on mount with loading state
- Frontend: Add validateSession API function
- Docs: Update Features.md with session validation behavior
- Docs: Update Web-Development.md with session validation pattern

Handles three outcomes:
1. Valid session (200): Proceed with cached state
2. Invalid session (401): Clear sessionStorage and redirect to login
3. Network error: Don't logout (backend may be temporarily unreachable)

045c8048fe Refactor: Replace inline style objects with makeStyles classes
Moved all static layout properties (display, gap, margin, padding, colour)
from inline style props to makeStyles classes in:

- MapBansTable.tsx: Pagination row flexbox layout
- JailDetailPage.tsx: Link styling for textDecoration
- HistoryPage.tsx: Summary text styling
- IpDetailView.tsx: Loading container and text formatting

Kept inline styles only for genuinely dynamic values:
- WorldMap.tsx: Tooltip position (follows mouse)
- TopCountriesPieChart.tsx: Legend color (from recharts data)
- TopCountriesBarChart.tsx: Chart height (derives from data length)

This change improves performance by leveraging Griffel's atomic CSS cache
and ensures consistency with the established Fluent UI pattern.

Updated Docs/Web-Development.md with explicit rule: inline styles only
for runtime-dynamic values, all static properties go in makeStyles.

69a0296c47 T-18: Merge useDashboardCountryData and useMapData into shared base hook
Create useBansByCountry as the shared base hook containing all common
fetch logic, abort-controller pattern, and state management. Both
useDashboardCountryData and useMapData now wrap this base hook:

- useDashboardCountryData: Thin wrapper that calls base hook with autoFetch=true
- useMapData: Wraps base hook with 300ms debounce layer

Changes:
- Create useBansByCountry.ts (base hook with optional autoFetch parameter)
- Refactor useDashboardCountryData.ts to use base hook
- Refactor useMapData.ts to use base hook with debounce wrapper
- Add tests for all three hooks

Benefits:
- Single source of truth for ban-by-country logic
- Bug fixes in base hook apply to both consumers
- Eliminates code duplication (~80 lines reduced)
- Maintains backward compatibility: existing call sites work unchanged

6a062a72a7 refactor: move jail detail sub-sections from pages/jail to components/jail
Move reusable UI section components (JailInfoSection, PatternsSection,
BantimeEscalationSection, IgnoreListSection, CodeList) from pages/jail/
to components/jail/, aligning with the project convention that pages/
contains only route-level entry points while components/ contains reusable
UI building blocks.

Changes:
- Move 5 section components + jailDetailPageStyles.ts to components/jail/
- Update import paths in moved components (relative paths to commonStyles)
- Update JailDetailPage.tsx imports to reference components/jail/
- Delete empty pages/jail/ directory
- Document pages/ vs components/ distinction in Web-Development.md

All components use standard import structure and TypeScript passes type
checking. BannedIpsSection was already correctly placed in components/jail/.

8d30a81346 feat(hooks): consolidate data-fetching patterns with useListData and usePolledData
- Refactor useJails (useJailList.ts) to use useListData with onSuccess for total
- Refactor useBanTrend to use useListData with onSuccess for bucket_size
- Refactor useDashboardCountryData to use useListData with onSuccess for aggregated data
- Refactor useHistory to use useListData with proper abort guard in finally()
- Create usePolledData for single-item endpoints with polling and window focus refetch
- Refactor useServerStatus to use usePolledData for 30s polling + window focus refetch
- Keep useIpHistory with manual pattern (single-item, no list semantics)
- Document deferred refactoring of useJailDetail (depends on T-13 for data/command split)

All data-fetching hooks now follow one of two consistent patterns:
1. useListData: for paginated/list endpoints with refresh semantics
2. usePolledData: for single-item endpoints with polling and focus-refetch

This eliminates code duplication, centralizes abort-guard logic, and enables
consistent fixes across all data-fetching hooks.

Resolves T-12.

8904e180d1 Fix: Prevent session-expiry errors from briefly showing in useConfigItem.save()
When save() encounters a 401 or 403 error, the HTTP client dispatches
SESSION_EXPIRED_EVENT which triggers auth handling and navigation to login.
However, setSaveError was called first, causing a brief flash of an
'Unauthorized' message before the redirect.

Now, isAuthError(err) checks if the error is a 401/403 before setting
saveError. Auth errors are rethrown without setting error state, allowing
the auth handler to deal with session expiry cleanly without UX confusion.

- Import isAuthError from api/client in useConfigItem hook
- Check for auth errors in the save() catch block before setSaveError
- Add tests for 401 and 403 error handling

6d5be523ab fix: KVEditor effect dependency uses stable JSON serialization
Replace the flawed join-based comparison (entryKeys.join(',')) with
JSON.stringify() to properly handle keys containing commas. The previous
implementation could produce false equality when different key sets
shared the same comma-separated representation (e.g., 'a,b' key vs
separate 'a' and 'b' keys).

This ensures the effect fires correctly when keys change, fixing silent
failures to update derived state.

f3d6574160 Fix misleading auth token storage in sessionStorage
- Remove JWT token and expires_at from sessionStorage
- Simplify AuthProvider to use boolean isAuthenticated flag
- Persist only isAuthenticated boolean for page-reload continuity
- Update AuthProvider test to verify new auth model
- Add comprehensive auth documentation to Web-Development.md explaining:
  - Cookie-based authentication model
  - How frontend auth state persists
  - Why tokens are no longer stored
  - Error handling flow for 401/403 responses

The authentication model is cookie-based: the backend sets bangui_session
cookie on login, frontend automatically includes it via credentials:
'include', and the backend is the sole authority on session validity.
Previously stored tokens were never actually used and made the auth model
misleading during development.

Fixes TASK-STATE-04.

10c534d090 Stabilize function references in useJails with useCallback
Previously, the withRefresh helper and all operations (startJail, stopJail, setIdle, reloadJail, reloadAll) were recreated on every render because they were defined in the hook body without useCallback. This caused unnecessary re-renders of child components using React.memo when parent state changed.

Now each operation is wrapped in useCallback with [load] as its dependency. This ensures function references remain stable between renders, allowing React.memo optimizations to work correctly in JailOverviewSection.

Tests confirm that function references are now stable between consecutive renders.

584588e363 fix: add AbortController and unmount guard to useIpLookup hook
- Add AbortController to cancel pending IP lookups when component unmounts
- Prevent state updates on unmounted components by checking abort signal before setState calls
- Add useEffect cleanup that aborts pending requests on unmount
- Update lookupIp API function to accept optional AbortSignal parameter
- Converts callback-based fetch to async/await pattern for better control flow
- Aligns with other API functions that already support abort signals (fetchJails, fetchJailBannedIps)

Fixes TASK-ABORT-04

4e3f2005f9 fix: capture AbortController in local variable to avoid race condition in three hooks
TASK-ABORT-03: Fix stale abortRef read in .finally() callbacks

In useGlobalConfig, useServerSettings, and useJailConfigDetail hooks, the
.finally() block was reading abortRef.current instead of using the locally
captured controller reference. If load() is called while a fetch is in flight,
the previous fetch's .finally() would read the new controller (not aborted)
and prematurely clear the loading state while the new fetch is still pending.

Changes:
- useGlobalConfig.ts: use locally-captured ctrl in .finally() (line 46)
- useServerSettings.ts: use locally-captured ctrl in .finally() (line 50)
- useJailConfigDetail.ts: use locally-captured ctrl in .finally() (line 47)

All three hooks already use ctrl correctly in .then() and .catch() callbacks.

Documentation:
- Add 'AbortController in Hooks' section to Web-Development.md
- Explains the pattern and shows incorrect vs correct examples
- Prevents future regressions

0223cb12a4 fix(hooks): Forward abort signal to fetchBansByCountry in useDashboardCountryData
The useDashboardCountryData hook was creating an AbortController and checking
signal.aborted in callbacks, but was not passing the signal to the fetchBansByCountry
API call. This meant the HTTP request itself was never actually aborted.

Now the signal is forwarded, allowing proper request cancellation when the hook
unmounts or dependencies change.

5a6cb640d8 Add AbortSignal support to API functions for request cancellation
Add optional signal?: AbortSignal parameter to all API GET functions so they can be
cancelled when components unmount. This prevents state-update warnings and wasted
resources.

Changes:
- frontend/src/api/history.ts: fetchHistory, fetchIpHistory
- frontend/src/api/map.ts: fetchBansByCountry
- frontend/src/api/jails.ts: fetchJails, fetchActiveBans
- frontend/src/api/config.ts: fetchJailConfig, fetchInactiveJails, fetchJailConfigFiles,
  fetchFilterFiles (threads signal through fetchFilters), fetchFilterFile, fetchActionFiles,
  fetchActionFile
- frontend/src/api/blocklist.ts: fetchImportLog, previewBlocklist

Updated all calling hooks to pass the abort signal from their controllers:
- useHistory, useIpHistory
- useMapData
- useActiveBans
- useJails
- useConfigActiveStatus (fetchJails and fetchJailConfigs)
- useJailAdmin (fetchInactiveJails)
- useJailConfigDetail (fetchJailConfig)
- useImportLog (fetchImportLog)
- useBlocklists (previewBlocklist with AbortController)

Updated Docs/Web-Development.md to document the convention.

f0caa24d91 fix(ServerHealthSection): add debounce to linesCount input to prevent rapid API calls
- Introduce linesCountRaw state to capture raw input values
- Add handleLinesCountChange callback with 300ms debounce delay
- Reuse existing filterDebounceRef pattern with linesCountDebounceRef
- Guard against zero/negative values by enforcing minimum of 100 lines
- Update Select component to use debounced value and new handler
- Add comprehensive test coverage for debounce behavior and input validation

Fixes TASK-BUG-09: Typing '500' in the Lines field now fires single API
request instead of three (one per keystroke). This mirrors the existing
debounce pattern used for the filter input.

1510dfc851 fix(config): gate useJails() calls behind dialog open prop
Refactored AssignActionDialog and AssignFilterDialog to only render
dialog content when open=true. This prevents useJails() from being called
when dialogs are closed, eliminating unnecessary GET /api/jails requests.

Implementation uses inner components (AssignActionDialogInner,
AssignFilterDialogInner) that are only mounted when the dialog is open.
The Dialog wrapper remains in the outer component to preserve Fluent UI
animation behavior.

Fixed test setup for AssignFilterDialog to properly call
assignFilterToJail from the mocked onAssign callback.

Fixes TASK-BUG-08.

97d47fae81 fix(jails): consolidate useJails() calls to eliminate double HTTP request
TASK-BUG-07: Remove duplicate useJails() hook call on JailsPage

Previously, useJails() was called twice on page load:
1. In JailsPage to extract jailNames for BanUnbanForm
2. In JailOverviewSection to manage the jail table

This caused two parallel GET /api/jails requests on every page load.

Changes:
- Lift useJails() to JailsPage as the single source of truth
- Accept jail state as props in JailOverviewSection
- Thread all required state (jails, total, loading, error, and action
  handlers) down from JailsPage to JailOverviewSection
- Remove useJails hook import from JailOverviewSection

This consolidation reduces unnecessary HTTP requests and improves
page load performance, especially with many jails.

3024a4ef07 fix(config): re-sync JailConfigDetail form when jail prop updates from server refresh
When useJailConfigs performs a background refresh, it may deliver an updated
JailConfig object for an already-selected jail. Previously, JailConfigDetail
would continue displaying stale locally-edited form values because the component
only re-initialized on jail name changes (via the key prop), not on object
identity changes.

Added a useEffect that detects when the jail prop reference has changed
(indicating a server refresh) and automatically resets all form fields to the
new server state, but only if autoSave is idle and has no pending changes.
This prevents accidentally overwriting external changes when the user saves,
while still letting users continue editing unsaved changes without interruption.

The implementation:
- Tracks the last-synced jail object in a ref
- Compares incoming jail reference to detect server updates
- Checks autoSave status to ensure no pending saves
- Verifies that current form state matches the old jail values
- Resets all 20+ form fields when conditions are met

1d50bc1a73 fix: add validation error handling to InactiveJailDetail
- Add validationError state to show network/API failures to user
- Use handleFetchError to properly handle auth errors (suppress generic error banner, trigger session-expiry flow)
- Clear validationError when user clicks Validate again
- Ensure error MessageBar renders instead of success banner when validation fails
- Fix InactiveJailDetail onValidate to return Promise as expected by prop type
- Fix useJailConfigs test to use correct JailConfig interface

Fixes TASK-BUG-05: prevents silent validation failures where user cannot distinguish between clean 'no issues' result and server error.

649ebf2dc7 fix: preserve zero values in autoSavePayload
TASK-BUG-04: The autoSavePayload was using the || operator to fall back
to server values when ban_time, find_time, or max_retry were empty or zero.
This silently dropped user intent to set these fields to 0, which is a
valid and meaningful value in fail2ban (e.g., ban_time=0 means permanent ban).

Replace the || fallback with explicit NaN and empty-string guards that
only fall back when:
1. The trimmed input is empty (user cleared the field)
2. The input is non-numeric (NaN)

This preserves valid zero values while still falling back appropriately
for invalid input.

- ban_time: 0 now correctly sends permanent ban instead of falling back
- find_time: 0 now sends the intended value instead of falling back
- max_retry: 0 now sends the intended value instead of falling back

Added comprehensive tests for:
- Preserving zero values in the payload
- Falling back for empty input
- Falling back for non-numeric input

d1674add90 fix: Stop MapPage pagination resetting on every data refresh
Remove 'bans' from the useEffect dependency array that resets pagination.
Since 'bans' changes with every background data refresh (new array reference),
the page was being reset to 1 every 30 seconds, making the table unusable for
pagination beyond the first page.

Add a separate effect that clamps the current page to totalPages when the
data shrinks below the current page offset (edge case when filtered results
are fewer than displayed page).

Fixes TASK-BUG-03.

0bfa975222 Fix: Keep ConfigPage tabs mounted to preserve form state
Previously, the tab content wrapper used 'key={tab}' which caused React to
unmount and remount the entire subtree when switching tabs. This destroyed
all component state, including unsaved form data and pending auto-saves.

Changes:
- Removed 'key={tab}' from the wrapper div
- All tab panels now render at page initialization
- Inactive tabs use CSS 'display: none' to hide without unmounting
- Tabs remain mounted throughout the page lifetime
- Users can now switch tabs without losing form input

Updated ConfigPage.test.tsx to reflect that inactive tabs remain in the DOM
(just hidden with CSS) rather than being removed entirely.

Documentation: Added 'Tab Panels' section to Web-Development.md
explaining the rule and rationale.

0f261e31c2 Fix infinite re-fetch loop in useJailConfigs
The hook was passing an inline onSuccess callback to useListData, which
included onSuccess in its internal refresh function's dependency array.
This caused refresh to be recreated on each render, which triggered the
useEffect, which fired the fetch, which completed and caused a re-render,
creating an infinite loop.

Wrap onSuccess in useCallback with empty dependencies so it maintains a
stable reference across renders. This allows refresh to be stable when
its dependencies don't change, breaking the cycle.

Add documentation to Refactoring.md explaining the onSuccess stability
requirement for useListData callers.

Also add tests for useJailConfigs to verify it doesn't trigger infinite
refetches with stable onSuccess callback.

0481810226 Fix open redirect vulnerability in LoginPage
Validate the ?next= query parameter to prevent open redirects to
external URLs. The parameter is validated to ensure it is a relative
path (starts with / but not //) before using it for navigation.
Invalid paths fall back to '/'.

This prevents attackers from crafting login links like /login?next=https://evil.com
that would transparently redirect authenticated users to malicious sites.
