Checkpoint: Modification de la page Factures avec sélection multiple et export PDF.

Nouvelles fonctionnalités :
- Ajout du champ exportStatus dans la base de données (exported/not_exported/export_error)
- Cases à cocher pour sélection multiple des factures
- Case "Tout sélectionner" (sélectionne uniquement les factures avec score 100%)
- Nouveau système de statuts : Exporté (vert), Non exporté (bleu), Erreur export (rouge)
- Bouton "Exporter" avec compteur de factures sélectionnées
- Validation stricte : seules les factures avec score de qualité 100% peuvent être exportées
- Les factures non éligibles (score < 100%) sont grisées et non sélectionnables
- Téléchargement automatique des PDFs des factures sélectionnées
- Message d'information expliquant la règle des 100%

La page affiche maintenant le statut d'export au lieu du statut de traitement, conformément aux spécifications.
