feat(sat): add API endpoints for FIEL and SAT sync (Phase 7)

- Add FIEL controller with upload, status, and delete endpoints
- Add SAT controller with sync start, status, history, and retry
- Add admin endpoints for cron job info and manual execution
- Register new routes in app.ts
- All endpoints protected with authentication middleware

Endpoints added:
- POST /api/fiel/upload
- GET /api/fiel/status
- DELETE /api/fiel
- POST /api/sat/sync
- GET /api/sat/sync/status
- GET /api/sat/sync/history
- GET /api/sat/sync/:id
- POST /api/sat/sync/:id/retry
- GET /api/sat/cron
- POST /api/sat/cron/run
