fix: add missing database commit and remove unused agent service files

- Add conn.commit() to agent registration in agent-registry
- Remove unused integration_layer.py and coordinator.py from agent-services
- Fix blockchain RPC endpoint from /rpc/sync to /rpc/syncStatus
- Replace Annotated[Session, Depends(get_session)] with Session = Depends(get_session) for cleaner dependency injection syntax across marketplace routers
