Refactor noble cluster configurations by removing deprecated Argo CD application management files and transitioning to a streamlined Ansible-driven installation approach. Update kustomization.yaml files to reflect the new structure, ensuring clarity on resource management. Introduce new namespaces and configurations for cert-manager, external-secrets, and logging components, enhancing the overall deployment process. Add detailed README.md documentation for each component to guide users through the setup and management of the noble lab environment.

+# helm upgrade --install kyverno-policies kyverno/kyverno-policies -n kyverno \
+#   --version 3.7.1 -f clusters/noble/apps/kyverno/policies-values.yaml --wait --timeout 10m
+#
+# Default profile is baseline; validationFailureAction is Audit so existing privileged
+# workloads are not blocked. Kyverno still emits PolicyReports for matches — Headlamp
+# surfaces those as “policy violations”. Exclude namespaces that intentionally run
+# outside baseline (see namespace PSA labels under clusters/noble/apps/*/namespace.yaml)
+# plus core Kubernetes namespaces and every Ansible-managed app namespace on noble.
+#
+# After widening excludes, Kyverno does not always prune old PolicyReport rows; refresh:
+#   kubectl delete clusterpolicyreport --all
+#   kubectl delete policyreport -A --all
+# (Reports are recreated on the next background scan.)
+#
+# Exclude blocks omit `kinds` so the same namespace skip applies to autogen rules for
+# Deployments, DaemonSets, etc. (see kyverno/kyverno#4306).
