ArgoCD only builds a helm-pull command for oci:// sources when the repo is
registered with enableOCI: true; otherwise it falls back to classic --repo
handling, which errors on an oci:// URL. Registered via configs.repositories
in argocd's own values.yaml (Git-managed), Application source updated to
the bare host/path form ArgoCD expects for OCI repos.
Prevents perpetual OutOfSync on bgppeers.metallb.io and other metallb CRDs caused by apiserver-populated .status fields not present in the Helm chart source.
