fix(comfyui): one ingress for the app and the login path

Two Ingresses on one host do not merge annotations. nginx applies the annotations
of a single ingress per host, so the separate /oauth2 object silently dropped the
auth_request on the app ingress: every request fell through to the backend and
ComfyUI answered 404 for the site root.

Move /oauth2 and / into the same ingress, so the auth annotations and both paths
belong to one object.
