Replace QAbstractListModel with QQuickFolderListModel in Component Casting

QAbstractListModel *flm = qobject_cast<QAbstractListModel*>(component.create()); 

This needs to be updated to cast to QQuickFolderListModel instead, as the model should now handle folder listings with an additional description property. The update requires revising the casting, ensuring that the new QQuickFolderListModel is properly integrated, and that the description field is added and managed correctly across the component.
