Bind each service's operator Role to a ServiceAccount alongside the
existing oidc:*-admins Group, and wire serviceAccountName into the
pods we control (immich-server, immich-machine-learning,
management-service). poimen-memory's Deployment lives in its own
repo/ArgoCD app, so its SA is created here but not yet wired to a pod.
Follows the portainer/kmsvc/temporal pattern - group + "permissions"
claim entry only, no Authentik Application/OAuth provider, since
poimen-memory is an internal API-key service, not browser OIDC login.
rock gets it automatically (already in every service_admin_group).
