feat: E-Flex - sauvegarde PaymentMethod CB + echeances auto (1ere +2j, suivantes tous les 2 mois)

- Checkout Session avec setup_future_usage=off_session + customer Stripe
  pour sauvegarder la carte et permettre les prelevements futurs
- Webhook payment_intent.succeeded stocke le PaymentMethod sur EFlex
  si pas deja configure (permet cron auto ensuite)
- 1ere echeance = creation +2 jours (pas de champ startDate)
- Echeances suivantes = tous les 2 mois apres la 1ere
- Retrait du champ date 1ere echeance du formulaire (automatique)
- Info dans le formulaire: "La 1ere echeance sera due 2 jours apres
  la signature. Les suivantes tous les 2 mois."
