Fix Hive deployment: add placement constraints to walnut node

- Force backend and frontend services to run on walnut where images are built
- Fixes 'No such image' errors on other nodes
- Both services now running successfully (1/1 replicas)
- Frontend accessible at https://hive.home.deepblack.cloud
- Backend API responding on /api/ endpoints
