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.

-	- Large prop chains increase coupling and refactor cost.
-- Goal:
-	- Move jail state/actions into dedicated context or controller hook.
-- What to do:
-	- Introduce JailContext (or equivalent local state container).
-	- Remove multi-hop prop forwarding.
-- Possible traps and issues:
-	- Context overuse can trigger broad rerenders if not split.

 **Example:** `BannedIpsSection` lives in `components/jail/` (not `pages/jail/`) because it is a reusable UI section that presents banned IPs. If a future report or dashboard also needed to show banned IPs, the same component could be imported and reused. By contrast, `JailDetailPage.tsx` lives in `pages/` because it is the top-level route component.
 
+### Tab Orchestration — ConfigPage Example
+
+When a page contains tab-based navigation (like the configuration page), isolate routing and tab state management into a dedicated **container component** to prevent the page from becoming over-centralized. This pattern applies to any multi-tab page.
+
+**Architecture:**
+
+1. **Page component** (`ConfigPage.tsx`) — renders page layout (header, title, description) and delegates tab routing to a container.
+2. **Container component** (`ConfigPageContainer.tsx`) — orchestrates tab navigation, manages which tab content is visible, and routes tab selection events.
+3. **Tab router hook** (`useTabRouter.ts`) — encapsulates tab state synchronization with browser history and supports deep linking (e.g., navigating directly to a specific tab with optional active item like a jail name).
+4. **Tab components** (`JailsTab.tsx`, `FiltersTab.tsx`, etc.) — domain-specific tab content; each is fully self-contained and receives tab-specific props only.
+
+**Component tree:**
+```
+ConfigPage (page layout)
+└── ConfigPageContainer (tab orchestration)
+    ├── useTabRouter (routing logic)
+    ├── JailsTab (jail editing UI)
+    ├── FiltersTab (filter editing UI)
+    ├── ActionsTab (action editing UI)
+    ├── ServerTab (server settings UI)
+    └── RegexTesterTab (regex testing UI)
+```
+
+**Benefits:**
+- **Focused pages** — `ConfigPage` renders only layout; routing logic is in the container.
+- **Reusable routing** — `useTabRouter` can be used by other pages with tab navigation.
+- **Isolated tabs** — each tab is a focused component; no shared state entanglement.
+- **Deep linking** — tab state is synchronized to browser history, allowing bookmarkable URLs and the back/forward buttons to work correctly.
+
+**Key pattern:**
+
+```tsx
+// hooks/useTabRouter.ts — routes and state
+export type ConfigTabId = "jails" | "filters" | "actions" | "server" | "regex";
+
+export function useTabRouter(): { activeTab: ConfigTabId; selectTab: (tab: ConfigTabId) => void; ... } {
+  const location = useLocation();
+  const navigate = useNavigate();
+  // Sync tab state to location.state for deep linking
+  // ... (see implementation)
+}
+
+// components/config/ConfigPageContainer.tsx — renders tabs
+export function ConfigPageContainer(): JSX.Element {
+  const { activeTab, selectTab } = useTabRouter();
+  return (
+    <>
+      <TabList selectedValue={activeTab} onTabSelect={...}>
+        {/* Tabs */}
+      </TabList>
+      {/* Tab content panels, conditionally rendered via CSS */}
+    </>
+  );
+}
+
+// pages/ConfigPage.tsx — layout only
+export function ConfigPage(): JSX.Element {
+  return (
+    <div>
+      {/* Page header, title, description */}
+      <ConfigPageContainer />
+    </div>
+  );
+}
+```
+
+**Avoid:**
+
+- Mixing page layout, tab orchestration, and tab content in one file.
+- Duplicating tab state across multiple hooks or components.
+- Hardcoding tab IDs as strings — use the `ConfigTabId` type.
+
 ### Separation of Concerns
 
 - **Pages** handle routing and compose layout + components — they contain no business logic.
