Moves the Grafana Helm deployment and LDAP template out of
ericomeehan.eom into its own role, and:
- maps cn=DevOps Members,ou=Teams to Editor in the DevOps org (org 2),
after DevOps Owners so owners keep Admin
- pins chart 11.4.2 from Bitnami's OCI registry (the HTTP index no
longer carries it) so redeploys don't upgrade to Grafana 12
- pins the bitnamilegacy/grafana image the cluster is already running
