fix: botones start/stop/restart usan POST; agrega webhook Coolify

- CoolifyApplicationStart/Stop/Restart cambian GET → POST (Coolify API requiere POST)
- Nuevo endpoint público POST /webhooks/coolify para recibir notificaciones
  de deployment/restart desde Coolify Settings → Notifications → Webhook
- UI: muestra URL del webhook en modal de config para fácil copia
