chore : bump version to v1.9.26

- Parc Machines transformé en DataTable avec filtres (site, date création, recherche)
- Vue d'ensemble : ajout filtre par plage de dates de création
- Activity-log : correction des liens entités (routes singulier sans /edit, ajout machine/document/model_type)
- ComponentItem & PieceItem : refonte complète des cartes dépliantes (design industriel raffiné)
  - Header compact avec tags colorés contrastés (référence, réf. auto, prix, produit, champs machine)
  - Panneau déplié structuré en sections avec mini-headers
  - Bordure gauche primary pour hiérarchie visuelle
- Ajout referenceAuto dans header et infos pour composants et pièces
- Suppression double encadrement ComponentHierarchy
