Admins can toggle maintenance mode from the admin dashboard (new
"Wartung" tab). When active, all non-admin users see a full-page
maintenance screen instead of the app.
- Backend: GET /api/config/service-mode endpoint (authenticated)
- Backend: stores state in app_settings key 'service_mode'
- Frontend: ServiceModeGuard wraps all ProtectedRoutes
- Frontend: ServiceModePage full-screen maintenance UI
- Frontend: ServiceModeTab in admin dashboard with toggle + message
- Admins (dashboard_admin group) always bypass the guard

PostgreSQL forbids volatile functions in partial index predicates.
Replace with two plain indexes on starts_at and ends_at instead —
the active-banner filtering is handled in the query WHERE clause.

Layout:
- Remove Container maxWidth cap so widgets scale fluidly on wide screens
- Fix ActivityFeed Card missing height:100% and overflow:hidden that caused
the timeline connector pseudo-element to bleed outside the card boundary
Performance (frontend):
- Migrate VehicleDashboardCard, EquipmentDashboardCard, AtemschutzDashboardCard,
UpcomingEventsWidget, and PersonalWarningsBanner from useEffect+useState to
TanStack Query — cached for 5 min, so navigating back to the dashboard no
longer re-fires all 9 API requests
- Add gcTime:10min and refetchOnWindowFocus:false to QueryClient defaults to
prevent spurious refetches on tab-switch
Backend stability:
- Raise default RATE_LIMIT_MAX from 100 to 300 req/15min — the previous limit
was easily exceeded by a single active user during normal dashboard navigation
- Increase DB connectionTimeoutMillis from 2s to 5s to handle burst-load
scenarios where multiple requests compete for pool slots simultaneously
