feat: add ServiceAccounts for poimen-memory/kmsvc/immich operator Roles

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.
