In Dokploy, services with a domain join the shared dokploy-network, where
another project also has an `api`. nginx proxied /api to `api:3000`, so
Docker DNS returned both containers and half of the requests went to the
other app: 404 "Cannot POST /api/auth/token" on sign-in and "sign-in not
configured" when /api/auth/config was answered by it.
Services now get task-stream-* aliases on the project network and nginx and
the API use them (task-stream-api, -postgres, -mongo, -redis). The API's
OPENAPI_FILE is empty in the container; docs 07 explain the aliases.
