Enable cert-manager for admission webhook TLS in kube-prometheus-stack values.yaml to prevent Kyverno pre-hook Job failures during Argo sync. Update noble-platform.yaml to adjust Helm chart sources and maintain proper order for Kyverno and kube-prometheus-stack, ensuring correct resource management and deployment flow.
