Subject: [PATCH] fix(demo): resolve DashboardGridDemo RenderFragment compile
 errors

Refactor data-driven widget rendering in DashboardGridDemo.razor to use valid RenderFragment helper methods instead of invalid Razor markup inside lambda switch arms.
Preserves existing UI behavior while fixing Razor/C# parsing issues and restoring successful build.
