Move band layout init to OnAfterRenderAsync on first render

Moved InitializeBandLayoutAsync() from OnInitializedAsync() to OnAfterRenderAsync() in CatalogsGrid.razor and MassDataGrid.razor. Now initialization occurs only on first render, followed by StateHasChanged(), to ensure proper layout setup after initial rendering. This addresses potential timing or rendering issues.
