Problem: Frontend JS bundle used credentials:'same-origin' which
dropped cookies on cross-domain requests. Login worked (200) but
the subsequent /auth/me check returned 401, leaving the user stuck
on the login screen.
Fix:
- AuthController now sets a dtp_jwt HttpOnly cookie on login/refresh
- Cookie uses Domain=.fahrschultermin.de (shared between frontend
and api subdomain), Secure, SameSite=Lax, Max-Age=8h
- JwtMiddleware reads JWT from Authorization header OR cookie
- Added AuthController::me() endpoint (was missing, caused 500)
- Logout endpoint clears the cookie
- Frontend index.php patches fetch() to use credentials:'include'
for all /api/v1/* calls
- Add hasStudentConflict() to Appointment model
- Check student conflicts in store() and update()
- Returns 409 Conflict when student has overlapping appointment
- Fixed PostgreSQL sequence for appointments id
- Move JWT_SECRET from hardcode to .env (security)
- Add hasInstructorConflict() to Appointment model
- Add conflict check in store() and update() — returns 409
- Add .env.example with placeholder
- Add API documentation (README.md)
- Add deploy_api.sh script
