Jose Diaz-Gonzalez ec7841a07b fix: inject placeholder listener for pre-validation upstream blocks ...

When pre-validating a custom nginx.conf.sigil before the build phase, no app listeners exist yet on first deploys. Templates that emit `proxy_pass http://app-port` while gating the matching upstream block on `DOKKU_APP_WEB_LISTENERS` render an undefined upstream, causing `nginx -t` to fail with "host not found in upstream". Pre-validation now passes a `127.0.0.1:5000` placeholder for `DOKKU_APP_WEB_LISTENERS` so the upstream block emits a static server entry and the template can be validated for syntax without depending on live listeners.
