Complete cert-manager Argo CD ownership

+The former `cert-manager-deployment` repository and its direct Kubernetes CI
+writer have been retired and archived; its CI kubeconfig secret and deployer
+RBAC are removed. Argo CD now owns the complete declarative cert-manager
+configuration with automated sync, self-heal, and pruning. The
+`watschn.studio` domain is no longer controlled, so its DNS-01 renewal cannot
+complete. Its current Certificate remains Ready with the existing TLS Secret,
+but the renewal challenge keeps this Application's health at Progressing. We
+are retaining that Certificate and Secret for now rather than risking an
+unreviewed TLS-resource deletion; remove them only if the service/domain owner
+confirms they are no longer needed.
