feat: integrate all backend APIs into frontend apps

- Fix API service paths to use /v1/iam/, /v1/dimentorin/, /v1/gacha/, /v1/hackathon/ prefixes
- Add roles, permissions, events, testimonials, sessions API services and hooks
- Rewrite gacha service with full CRUD + roll/claim endpoints
- Replace all mock data in backoffice pages with real API calls (accounts, roles, permissions, gacha-roll, dashboard, sessions, users-dimentorin, feedback-review, settings)
- Wire dimentorin mentoring list to useMentorList with search + pagination
- Wire dimentorin mentor detail page to useMentorById, pass real data to all sections
- Wire appointment modal to useBookSession with controlled schedule inputs
- Wire gacha app Spin Now to useExecuteGachaRoll, show credits and real items
