Automate Prowler MANUAL finding verification (#335)

## Summary
- Adds automated node-level verification to `review-compliance-reports`: kubelet file perms/ownership, kubelet config args, etcd CA separation, RBAC cluster-admin bindings
- Mutes the 14 MANUAL Prowler findings via new `manual-node-checks.yaml` mutelist file
- New `node-config-automated-verification` compensating control documents the approach
- Script fails loudly (red FAIL + verdict panel) if any check deviates from expected values

## Test plan
- [x] `mise run review-compliance-reports` — all 12 node checks PASS
- [x] Injected bad expected value (perms 400 vs actual 600) — FAIL rendered correctly
- [x] Fixed colon-in-binding-name bug (kubeadm:cluster-admins) with tab-separated jsonpath
- [ ] After merge: sync prowler mutelist ConfigMap and verify next scan shows 0 MANUAL findings

## Note
Prowler coverage is minikube-indri only — ringtail/k3s is a known gap tracked separately.

Automate verification of Prowler MANUAL findings (kubelet file perms, kubelet config, etcd CA, RBAC cluster-admin) in `review-compliance-reports` and mute them with `node-config-automated-verification` compensating control.
