Subject: [PATCH] Refit: retarget net10.0, Refit 15.2.0,
 AddRefitGeneratedClient, error-handling and headers samples

- RefitLibrary and Tests retargeted net6.0 -> net10.0
- Refit and Refit.HttpClientFactory 6.3.2 -> 15.2.0
- Microsoft.Extensions.Hosting 6.0.1 -> 10.0.0
- Microsoft.AspNetCore.Mvc.Testing 6.0.5 -> 10.0.0
- Microsoft.NET.Test.Sdk 16.11.0 -> 17.11.1
- Program.cs registers with AddRefitGeneratedClient<IUsersClient>(); on Refit 15.x
  AddRefitClient<T>() throws NotSupportedException without the opt-in
  Refit.Reflection package
- IUsersClient gains an ApiResponse<User> endpoint, a query-string plus
  CancellationToken overload, and an interface-level [Headers] attribute;
  Program.cs shows the ApiResponse call site
