flexible model with schedule slots. This commit removes all Programs
code across frontend and backend:
Frontend:
- Delete admin-program-form component (ts/html/scss)
- Delete program.service.ts and program.ts interface
- Remove Programs tab, form modal, and all CRUD logic from admin
component (ts + html)
Backend:
- Delete programs API router
- Remove Program ORM model and ProgramCreate/Update/Response schemas
- Remove programs router registration from main.py
- Remove Program from seed data, seed helpers, and truncate/reset
