Call web API article updates

[guardrex]

Fixes #31887

I haven't reached security updates yet. Security updates will be handled by a separate issue/PR shortly.

This is going in NOW 🚑🚒🚓 to surface better coverage and the sample apps quickly. I'll be circling around for more updates and to address security guidance for calling web APIs shortly ... by the EOW hopefully 🤞🍀.

The sample apps are here ...

• Blazor WASM with a separate backend web API for todo list web API

  https://github.com/dotnet/blazor-samples/tree/main/8.0/BlazorWebAssemblyCallWebApi

• Blazor Web App with the separate backend todo list web API (uses HttpClient server and client to interact with it) AND a separate movie list web API that resides in the server project of the BWA. For movie list interaction, the components use either the client-based service to access the web API with HttpClient or the server-based service to interact directly with the movie data on the server.

• Included Dan's sample that performs streaming rendering
