Inventaire depuis une commande

- Possible de générer un inventaire à partir d'une commande passée.
  Préremplissage avec les valeurs commandées.
- Possible d'indiquer les prix d'achat pour avoir l'historique des prix
  d'un article chez un fournisseur. Et bientôt, une proposition
  automatique de prix.
- L'erreur sur le stock d'un article lors d'un inventaire n'est pas mise
  à jour dans le cas où l'inventaire est généré à partir d'une commande.
- Ajout d'un champ `at` au modèle `SupplierArticle` afin de conserver
  l'historique des prix d'achat
- Fix sur la vue `order_create`
