Two defects in the ksops generator:
1. The `zitadel-masterkey.enc.yaml` entry was added with two-space indentation
while every other entry uses four. YAML rejected the list, and kustomize
reported it as `loading generator plugins ... MalformedYAMLError: yaml: line
39`. That failed the whole sops-secrets application, so no Secret in that app
could be created. Verified by running the same kustomize build inside
argocd-repo-server: exit 1 before the fix, exit 0 with 33 manifests after it.
2. The masterkey value was generated during the first verification pass and
appeared in that session's output. Rotate it now, before the instance exists:
a fresh 32-byte value, SOPS-encrypted, with the offline copy updated. No
ZITADEL data exists yet, so rotation costs nothing. After the first sync it
would mean re-encrypting system.encryption_keys.
The offline copy lives outside the repo at ~/zitadel-masterkey.offline (0600).
