feat(contribution): add CDC sync status API and fix deploy script timing

- Add initialSyncCompleted flag to track CDC sequential sync completion
- Add getSyncStatus() method to CDCConsumerService
- Add /health/cdc-sync endpoint to expose sync status
- Update deploy-mining.sh to wait for CDC sync completion before calling publish APIs
