openclaw: reinstall limpio con Claude API y ArgoCD

- Manifiestos limpios: namespace, rbac, pvc (5Gi local-path), deployment, service, ingress
- nodeSelector chemavx-k8 en deployment para fijar PVC en el nodo correcto
- Imagen fijada a ghcr.io/openclaw/openclaw:2026.4.12
- Sin initContainers ni secrets en el deployment (config post-arranque via exec)
- Elimina artefactos: configmap-kube-root-ca.crt.yaml, serviceaccount-default.yaml, pvc-openclaw-pvc.yaml, rbac-openclaw-agent.yaml
- Añade argocd/application-openclaw.yaml para gestión GitOps
