fix(comfyui): keep the login path on an ungated ingress

Gating /oauth2 with the app redirects /oauth2/start to itself and the browser
loops. ingress-nginx applies an ingress's annotations to the locations that
ingress defines, so the login path belongs on its own object without auth-url.

This split failed once before, and the split was not the reason: the app ingress
carried a configuration-snippet that the controller rejects, which dropped that
whole object and left only the login path rendered.
