Vickey 04d0d5342f feat(data): add persistent state lease table for driver/device status

Replace local Caffeine cache as the source of truth for driver and
device online status with dc3_entity_state, a persistent state lease
table backed by PostgreSQL.

- Add EntityStateDO/Mapper/Manager persistence stack.
- Add EntityStateExpiryScanner that scans expire_time every 15 seconds
  with lease_version recheck to avoid stale alarm writes.
- Dual-write heartbeat path: DriverStateServiceImpl and
  DeviceStateServiceImpl now write dc3_entity_state first, then local
  cache.
- All status queries (controllers, gRPC server, local facade,
  SystemHealthServiceImpl) read from dc3_entity_state. Rows missing or
  past expire_time return offline.
- OfflineExpiryListener gains a DB dedup check to skip expiry events
  already handled by the scanner.
- Add @EnableScheduling to DataApplication.
- Add design doc docs/design/entity-state.md with full DDL.

This resolves restart state loss, multi-instance inconsistency, and
races between expiry checks and fresh heartbeats.
