fix: runAgent fire-and-forget + polling sur la page /agents

Le bouton Play des cartes agents appelait runAgent (Server Action) qui
attendait executeAgent (~2-5 min) → spinner bloqué sans résultat.

- runAgent retourne immédiatement { success, agentId }
- agent-card.tsx lance un polling toutes les 3s sur GET
  /api/agents/run-for-note?agentId= jusqu'au statut terminal
- Toast persistant Sonner pendant la génération, mis à jour au résultat
- Cleanup automatique du polling au démontage
