Add collapsible band editor to grid components

Browse Source 
Introduce a toggleable "Band-Layout konfigurieren" section in CatalogsGrid.razor and MassDataGrid.razor, allowing users to expand or collapse the band editor UI. Added bandEditorExpanded state to control visibility. Updated CSS to style the new toggle button and its expanded/collapsed states, improving usability and reducing UI clutter.
