feat(stock): tri chronologique des bons et réouverture/historique des bons de confection

- Trie les bons de préparation (date) et de confection (created_at) par ordre chronologique FIFO
- Ajoute la réouverture a posteriori des bons de confection terminés avec régularisation automatique des stocks
- Ajoute le modèle ProductionOrderHistory et trace l'historique complet des modifications (statuts, composants, documents)
- Intègre le bouton de réouverture et la section d'historique dans les vues desktop et mobile
