chemavxandClaude Fable 5 e9eb8c4ae2 fix(backup-system): kubectl via ServiceAccount in-cluster, no kubeconfig del host
El k3s.yaml del host apunta a 127.0.0.1:6443 (inalcanzable desde el pod).
El script antiguo solo funcionaba porque su KUBECONFIG apuntaba a un
fichero inexistente y kubectl caia en fallback al SA. Se hace explicito:
unset KUBECONFIG + RBAC con apps/deployments,statefulsets get (para
kubectl exec deploy/...) y se retira el mount del kubeconfig.
