-# ArgoCD Server — Insecure Mode Patch

-# When TLS is terminated at the Gateway (not at argocd-server itself),
-# argocd-server must run in --insecure mode. Without this, it tries to
-# do double TLS and the Gateway connection fails.
-#
-# This patches the argocd-server Deployment to add the --insecure flag.
-# Applied as part of the argocd-config Application (same path/namespace).
