Add custom toolbar actions with icons to grids

Browse Source 
Introduce Add, Edit, and Delete buttons with Bootstrap Icons in the toolbars of CatalogsGrid and MassDataGrid. Hide the default command column by overriding ShowCommandColumn. Update BandGridBase to conditionally render the command column. Track focused row index for toolbar actions, enabling row operations via toolbar instead of the grid's built-in command column. Add Bootstrap Icons stylesheet to App.razor.
