refactor: renommer Order en Facture + meme OrderNumber partage entre Devis/Advert/Facture

Changement de modele:
- Le meme OrderNumber est partage entre Devis, Advert et Facture
  (ex: 04/2026-00001 pour les 3)
- Les relations OrderNumber passent de OneToOne a ManyToOne pour
  permettre le partage du meme numero

src/Entity/Order.php supprime, remplace par:
src/Entity/Facture.php (nouveau):
- orderNumber: ManyToOne vers OrderNumber (meme numero que l'Advert parent)
- advert: ManyToOne vers Advert (nullable)
- splitIndex: smallint, suffixe pour factures multiples sur un meme advert
  (0 = pas de suffixe, 1 = -1, 2 = -2, etc.)
- getInvoiceNumber(): retourne le numero complet avec suffixe si splitIndex > 0
  (ex: 04/2026-00001 ou 04/2026-00001-2)

src/Entity/Devis.php:
- orderNumber: OneToOne remplace par ManyToOne vers OrderNumber
- adverts: OneToMany vers Advert (inchange)

src/Entity/Advert.php:
- orderNumber: OneToOne remplace par ManyToOne vers OrderNumber
- orders: renomme en factures, OneToMany vers Facture

src/Repository/OrderRepository.php supprime, remplace par:
src/Repository/FactureRepository.php (nouveau)

migrations/Version20260402202809.php:
- Suppression table `order`, creation table facture
- Modification des contraintes unique sur devis et advert
  (unique index supprime car ManyToOne)
