feat: fichier filter dropdown + fonctionnel sur toutes les vues

- Dropdown Filter dans la toolbar (icône filtre, à côté de Sort)
- Menu avec Folders, Pages, PDF, Images, Code, Text + Clear filter
- doFilter() applique maintenant filterType au tree view via _filterTree()
- Filter chips visibles dans toutes les vues comme indicateur
- L'enhanced table prend le relais quand un filtre est actif dans les vues non-tree
