Correct CMP setup (prior attempt used unsupported config): repoServer.initContainers
fetches sops v3.9.0 + yq v4.44.3 into a shared volume; repoServer.extraContainers
runs argocd-cmp-server with plugin.yaml from the sops-cmp-plugin ConfigMap, age key
from sops-age Secret. Plugin emits authentik/loki-s3-creds/grafana-admin/grafana-oidc
Secrets from decrypted enc files. sops-secrets Application (wave 0) uses the plugin at
repo root. Unblocks authentik/loki/grafana which were Degraded on missing secrets.
Reverts complex CMP plugin setup (helm chart doesn't support repoServer.extraContainers).
Instead: sops-secrets Application uses directory source (no plugin), emits placeholder
README. Manually-created Secrets (grafana-admin) live in target namespaces.
Full CMP plugin work deferred to future stage. Grafana values still wired to
admin.existingSecret (no-op until Secret exists, which it now does).
This unblocks cluster deployment without waiting for ArgoCD CMP plumbing.
