feat(sat): add database models for SAT sync

Phase 1 - Database models:
- Add FielCredential model for encrypted FIEL storage
- Add SatSyncJob model for sync job tracking
- Add SAT-related enums (SatSyncType, SatSyncStatus, CfdiSyncType)
- Add TypeScript types in shared package
- Relations: Tenant -> FielCredential (1:1), Tenant -> SatSyncJobs (1:N)
