Add Blazor WASM .NET on Web Workers sample app

[guardrex]

Addresses dotnet/AspNetCore.Docs#36370

Ilona ...

• Please check the naming of the sample folders to see if they make sense. I'm aligning the two samples with similar naming: DotNetOnWebWorkersBlazorWebAssembly and DotNetOnWebWorkersReact.
• I updated the sample to 10.0 and added the Not Found features.
• I used a placeholder with the text <input> element so that one doesn't need to back out the text to type something in the field.
• Static analysis said to add await to InvokeAsync(StateHasChanged) in Home.razor.cs (I think because the method returns a Task).
• Other tiny nits here and there on spacing in the code for consistency with what we normally do.

I'll go work on the article next. I'll update the React sample name in the .NET on Web Workers article on the docs PR.

Pull Request Overview

This PR adds a comprehensive Blazor WebAssembly sample demonstrating .NET on Web Workers and updates the existing React sample with consistent naming. The samples show how to run .NET code on web workers to offload computation from the main UI thread, using QR code generation as a practical example.

Key Changes

• Adds DotNetOnWebWorkersBlazorWebAssembly sample with complete Blazor WASM implementation including worker infrastructure, UI components, and build scripts
• Renames React sample to DotNetOnWebWorkersReact for consistent naming across samples
• Updates both samples to target .NET 10.0 with appropriate package versions

After that small rename, it's working and looks good. Thanks!
