fix(funk-cluster): grep -c bug + uncordon automatique au démarrage

- check_k8s_pods : grep -c retournait "0\n0" (|| echo 0 inutile quand
  grep-c affiche 0 même en cas d'absence de match) — utilise un cache
  intermédiaire pods_output + running=$(grep -c) || running=0
- cmd_start : uncordon automatique si nœuds SchedulingDisabled détectés
  (séquelle d'un funk-stop --k8s), suivi d'une attente pod infra avant
  le check — évite de devoir passer --k8s juste pour débloquer le cluster
