feat: move profile completeness check from login to booking flow entry

- Add profileComplete flag to User entity to avoid API calls
- Set flag during login (BpnAuthenticator) and profile save
- Check flag in IndexController when entering booking flow
- Remove ProfileCompletionSubscriber (no longer needed)

Users with incomplete profiles are only redirected when starting
a new booking, not on every login. Eliminates extra API call by
caching completeness status on the user entity.
