Added isAuthReady state to prevent router from rendering before auth
state is initialized. This eliminates login redirect loops and ensures
deterministic auth behavior.
Changes:
- Added isAuthReady state (default: false)
- New useEffect to initialize auth before rendering
- Waits for refreshUser() to complete if tokens exist
- Shows loading screen while auth is initializing
- Always sets isAuthReady=true in finally block
Loading screen:
- Simple centered spinner with "Chargement..." text
- Uses Tailwind classes for styling
- Matches app theme (bg-background, text-muted-foreground)
Behavior:
- App loads → Check for tokens → If yes, await refreshUser()
- Only after auth check completes, render router
- Prevents "flash of login page" for authenticated users
- Eliminates race condition: router no longer renders before auth ready
Impact: Fixes intermittent login loops, improves UX on page refresh.
Fixes: P1.2 from audit AUDIT_TEMP_29_01_2026.md
- Added useQueryClient hook to App component
- Added setupReactQuerySync import and initialization
- Initialize sync on App mount with cleanup on unmount
- React Query cache synchronization now active across browser tabs
- Multi-tab updates work when mutations succeed or queries are invalidated
- Action 2.3.1.2 complete
