Cluster 2a (hlth-msmtp failed=65 in universal single-app deploys):
the health-check script sent "To: administrator" but the administrator
Unix user is only provisioned in server-pass, so postfix rejected the
recipient. Replace the inline Jinja conditional with a role-local
lookup plugin that picks administrator.email (external), "administrator"
(local + user exists) or "root" (local + missing).
Side change: SIM105 cleanup in utils/install/lint/__main__.py.
