feat: complete WorkProcessor integration and bug fixes

- Fix hourly lookback bug: use hourly timestamp/interval (not daily)
- Update DI registrations across DataSync, DataAccess, Api layers
- Add WorkProcessor config to appsettings.json
- Remove deprecated DataSyncService (replaced by WorkProcessor)

All 340 DataSync tests pass. Legacy bug from OLD solution now fixed.
