Checkpoint: Ajout de la configuration des champs obligatoires pour le score LLM

Nouvelle fonctionnalité permettant de configurer quels champs sont obligatoires ou optionnels pour atteindre un score de reconnaissance de 100%.

Modifications:
- Nouvelle table llmFieldsConfig dans la base de données
- Routes tRPC pour gérer la configuration (getAll, updateField)
- Interface utilisateur dans la page Paramètres avec tableau et cases à cocher
- Modification du code d'extraction pour générer dynamiquement l'instruction de score
- Initialisation automatique des champs par défaut (supplierName, invoiceNumber, invoiceDate, totalAmount obligatoires)
- Tests unitaires pour valider la fonctionnalité

L'utilisateur peut maintenant personnaliser quels champs doivent être détectés pour qu'une facture atteigne 100% de score.
