refactor: update deposit system with 24h no-show rule, optional forgiveness, and admin enforcement toggle

- Change no-show threshold from 12h to 24h for late cancellations
- Add optional forgive_no_show boolean to cancellation endpoint
- Add optional enforce_deposits boolean to admin booking creation
- Set deposits_required = 3 on no-show (not +=3) to prevent escalation
- Implement per-cancellation forgiveness instead of bulk forgiveness
- Remove ForgiveNoShowsForUser() function (now per-event)
- Admin can now bypass deposit checks when needed
- All changes backward compatible (nil defaults to enforce)
