Register print_forge for django deploy (closes #27) (#28)

## Summary
- Closes [#27](#27).
- Register `print_forge` in `app_catalog` (`type: django`, repo `ai_ml_operations/print_forge`, default branch `master`).
- Add `host_apps` prod `:8007` / beta `:8019` on **adama**, **roslin**, **starbuck**, **apollo**, and **ai-server-4080**.
- dj-queue **worker singleton on adama** only (`compose_profiles: [worker]`); other hosts web-only.
- Document ports, NPM hosts, Postgres DBs, secrets, Nominatim (`10.0.0.128:8089`), and the app-repo companion ([print_forge#1](ai_ml_operations/print_forge#1)).
- Update `scripts/deploy.sh` `--app` help.
- Move unused `abc_be` prod port reserve **8007 → 8009** so it does not collide with `print_forge`.

## Test plan
- [ ] Confirm `print_forge` appears in `app_catalog` and `--app print_forge` is listed in `deploy.sh --help`
- [ ] Confirm beta `host_apps` on all five hosts (port **8019**); adama has `compose_profiles: [worker]`
- [ ] Confirm prod port **8007** reserved on those hosts (no NPM until launch)
- [ ] After merge (ops, not this PR): create Postgres DBs `print_forge_beta` + `print_forge` on `10.0.0.230`, grant `westfarn`
- [ ] After merge (ops): write `~/Documents/secrets/print_forge/print_forge_{beta,prod}.env` from app `.env.prod.example`; add `print_forge:<token>` to `SHORTENER_API_TOKENS` (beta first)
- [ ] After merge (ops): NPM `print-forge-preview.aimloperations.com` → `:8019` active/active; do **not** NPM-route `printforgeprints.com` until launch
- [ ] After secrets + DBs: `~/Documents/repos/server-infra/scripts/deploy.sh --app print_forge --env beta --ref master` and hit `/healthz/`
