feat: Task 4 — paginated banned-IPs section on jail detail page

Backend:
- Add JailBannedIpsResponse Pydantic model (ban.py)
- Add get_jail_banned_ips() service: server-side pagination, optional
  IP substring search, geo enrichment on page slice only (jail_service.py)
- Add GET /api/jails/{name}/banned endpoint with page/page_size/search
  query params, 400/404/502 error handling (routers/jails.py)
- 23 new tests: 13 service tests + 10 router tests (all passing)

Frontend:
- Add JailBannedIpsResponse TS interface (types/jail.ts)
- Add jailBanned endpoint helper (api/endpoints.ts)
- Add fetchJailBannedIps() API function (api/jails.ts)
- Add BannedIpsSection component: Fluent UI DataGrid, debounced search
  (300 ms), prev/next pagination, page-size dropdown, per-row unban
  button, loading spinner, empty state, error MessageBar (BannedIpsSection.tsx)
- Mount BannedIpsSection in JailDetailPage between stats and patterns
- 12 new Vitest tests for BannedIpsSection (all passing)

/**
* Tests for the `BannedIpsSection` component.
*
* Verifies:
* - Renders the section header and total count badge.
* - Shows a spinner while loading.
* - Renders a table with IP rows on success.
* - Shows an empty-state message when there are no banned IPs.
* - Displays an error message bar when the API call fails.
* - Search input re-fetches with the search parameter after debounce.
* - Unban button calls `unbanIp` and refreshes the list.
* - Pagination buttons are shown and change the page.
