CONFIGURED - Wire docker-compose to Traefik for first deploy

- Join the app to the external proxy network and drop the published host port
- Add Traefik labels for mohfarawati.de, www, and root.mohfarawati.de
- Parametrize network/entrypoint/certresolver via TRAEFIK_* env with sane defaults
- Pass ADMIN_HOST to the app and document production env in .env.example
