feat: Docker deployment + Gitea CI/CD workflow

- Multi-stage Dockerfile: Node frontend build → Python wheel build → slim runtime
- Backend serves SvelteKit static output via FastAPI StaticFiles mount
- docker-compose.yml with named volume for /data persistence
- Gitea Actions workflow: build/push Docker image + create release on v* tags
- Add NOTIFY_BRIDGE_STATIC_DIR config for frontend path
- Fix run() to use configurable host/port
