AuthContext:
- Added setAuthFromToken() for direct token/profile set
- Used for email verification auto-login (no /login request)
- Properly initializes session with token and profile
Verify.jsx:
- Fixed auto-login: now uses setAuthFromToken() instead of login()
- Added "already_verified" status for better UX
- Auto-redirect to /login after 3s if already verified
- Shows friendly message instead of error
This fixes:
- 422 Unprocessable Entity error during auto-login
- Empty dashboard page after verification (now redirects correctly)
- "Ungültiger Link" error on second click (now shows "bereits bestätigt")
