feat: program management

- ProgramController: full CRUD, publish, close, delete (guarded if attendance exists)
- StoreProgramRequest + UpdateProgramRequest with Malay attribute names
- AuditLogService: logs admin actions, redacts sensitive fields (no_kp, token, password)
- Program index: search, status filter, pagination (Bootstrap 5)
- Program create/edit: shared _form partial with all fields (dates, sessions, walk-in toggle)
- Program show: tab layout (participants, qr, template, questionnaire, statistics)
- Bootstrap 5 pagination via Paginator::useBootstrapFive()
