Switch to Brian's registry at 192.168.86.11:30095, add CI build+push+deploy jobs

- All services pull from 192.168.86.11:30095 instead of localhost:5000
- Removed self-hosted registry container (Brian runs his own)
- CI workflows: test → build → push to registry → deploy
- build-push.sh and watch-loop.sh updated with new registry address
