Register disney_hotel_service for beta and prod deploy (#48)

## Summary
- Closes #47.
- Register `disney_hotel_service` (`DisneyHotel/disney_hotel_service`, branch `master`) for beta and prod on all five webservers.
- Prod port **8023**, beta port **8024** (8021/8022 stay WordPress `relawfirm`). Alert worker profile only on adama.
- Document Postgres databases `disney_hotel_service` / `disney_hotel_service_beta`, NPM hosts, and the control-node secret layout. This app reads `POSTGRES_*`, not `DATABASE_URL`.

## Test plan
- [ ] `disney_hotel_service` is in `app_catalog` and `./scripts/deploy.sh --help` lists it
- [ ] All five hosts have prod **8023** and beta **8024**; only adama sets `compose_profiles: [worker]`
- [ ] After merge (ops): create both databases on `10.0.0.230` and grant `westfarn`
- [ ] After merge (ops): write `~/Documents/secrets/disney_hotel_service/disney_hotel_service_{prod,beta}.env` (mode 600)
- [ ] After merge (ops): NPM `disneyhotel.app` (+ www) → `:8023`, `beta.disneyhotel.app` → `:8024`
- [ ] Deploy waits on `docker-compose.prod.yml` in the app repo (no bundled db, `${WEB_PORT}:8000`, worker profile `worker`)
