Decomisión de openclaw

- Elimina manifests openclaw/ y argocd/application-openclaw.yaml
- backup-system: fuera del backup diario, crown-jewels, expected y retain;
  fuera el mount hostPath del cronjob y la fila de RESTORE.md
- monitoring: eliminado panel openclaw del dashboard homelab-overview
- n8n: openclaw y polymarket fuera del health-check (espejo del workflow vivo)
- cluster-wide/namespaces.yaml: fuera openclaw + añadidos separadores '---'
  que faltaban (el archivo era un único doc YAML donde ganaba el último ns)

Cluster ya limpio: app ArgoCD, namespace, PVC/PV, RBAC cluster-scoped y
monitor de Uptime Kuma. Backup final: ~/decommissioned/openclaw-final-2026-07-18.tar.gz
