feat(operator): production build + k3s deployment

- Dockerfile for the operator app (same pattern as portal/booking).
- Env-driven auth/app base URLs in nuxt.config so one build serves
  dev (.local) and production (.eu).
- Deployment + Service + Ingress on operator.dezky.eu.
- Add operator to the typecheck matrix.
