Task 1: Move Configuration to last position in sidebar NAV_ITEMS
Task 2: Add automatic rollback when jail activation fails
- Back up .local override file before writing
- Restore original file (or delete) on reload failure, health-check
failure, or jail not appearing post-reload
- Return recovered=True/False in JailActivationResponse
- Show warning/critical banner in ActivateJailDialog based on recovery
- Add _restore_local_file_sync and _rollback_activation_async helpers
- Add 3 new tests: rollback on reload failure, health-check failure,
and double failure (recovered=False)
Task 3: Color pie chart legend labels to match their slice color
- legendFormatter now returns ReactNode with span style={{ color }}
- Import LegendPayload from recharts/types/component/DefaultLegendContent
- Install Recharts v3 as the project charting library
- Add chartTheme utility with Fluent UI v9 token resolution helper
and a 5-colour categorical palette (resolves CSS vars at runtime)
- Add TopCountriesPieChart: top-4 + Other slice, Tooltip, Legend
- Add TopCountriesBarChart: horizontal top-20 bar chart
- Add useDashboardCountryData hook (wraps /api/dashboard/bans/by-country)
- Integrate both charts into DashboardPage in a responsive chartsRow
(side-by-side on wide screens, stacked on narrow)
- All tsc --noEmit and eslint checks pass with zero warnings
