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.

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.

The Map tab provided a form for editing world-map color thresholds
(low, medium, high). Moving this into the Server tab consolidates all
server-side configuration in one place.
- Add map color thresholds section to ServerTab with full validation
- Load map thresholds on component mount with useEffect
- Implement auto-save for threshold changes via useAutoSave hook
- Display threshold color interpolation guide
- Remove MapTab component import from ConfigPage
- Remove 'map' from TabValue type
- Remove Map tab element from TabList
- Remove conditional render for MapTab
- Remove MapTab from barrel export (index.ts)
- Delete MapTab.tsx file
- Update ConfigPage test to remove MapTab mock
All 123 frontend tests pass.
Global tab provided the same four editable fields as Server tab:
log_level, log_target, db_purge_age, db_max_matches. Server tab already
has these fields plus additional read-only info (db_path, syslog_socket)
and a Flush Logs button.
- Add hint text to DB Purge Age and DB Max Matches fields in ServerTab
- Remove GlobalTab component import from ConfigPage
- Remove 'global' from TabValue type
- Remove Global tab element from TabList
- Remove conditional render for GlobalTab
- Remove GlobalTab from barrel export (index.ts)
- Delete GlobalTab.tsx file
- Update ConfigPage test to remove Global tab test case
All 123 frontend tests pass.
