fix: add towlion network to compose and fix postgres volume path (#1)

- Add towlion external network to app and celery-worker services in
  docker-compose.yml for multi-app routing via shared Caddy
- Remove host port binding (8000) from app service — Caddy routes
  traffic via the shared network
- Fix postgres volume path from /data/database to /data/postgres in
  docker-compose.standalone.yml to match bootstrap-server.sh
