Adds node-level checks (kubelet file perms/ownership, kubelet config args, etcd CA separation, RBAC cluster-admin bindings) to the weekly compliance review script, and mutes the 14 MANUAL findings in Prowler with a new node-config-automated-verification compensating control.

# Node-level and RBAC checks that Prowler reports as MANUAL because it
|
|
# cannot evaluate them from inside a pod. Compensated by automated
|
|
# verification in `mise run review-compliance-reports`, which SSHes into
|
|
# the minikube node and checks each condition directly every week.
