Revert "Add MVC support to Blazor 9 application" (PR #58)

This reverts merge commit 2feef52.

Removes:
- Controllers/HomeController.cs
- Views/* (Home/Index.cshtml, Home/About.cshtml, Shared/_Layout.cshtml, _ViewImports.cshtml, _ViewStart.cshtml)
- MVC_INTEGRATION.md
- IMPLEMENTATION_SUMMARY.md
- MVC configuration in Program.cs (AddControllersWithViews, MapControllerRoute, etc.)

Rationale: User requested to undo all changes from PR #58.

Restores the repository to pure Blazor 9 application without MVC support.
