Introduce a catalog-driven Tools Management section under Clusters so
admins can install/uninstall infrastructure tools per cluster: cert-manager
(Helm/jetstack), ClusterIssuer (email + HTTP01 form, depends on cert-manager),
and central Elasticsearch. Cluster creation no longer auto-installs Elastic
or the cloudhost-node-cluster-dns DaemonSet; build bootstrap stays automatic.
