Switch from Moq to NSubstitute in Csla.Blazor.WebAssembly.Tests

This commit represents a significant shift in the mocking framework used for unit testing in the `Csla.Blazor.WebAssembly.Tests.csproj` project. The `Moq` package has been replaced with `NSubstitute` in the project file and throughout the `SessionManagerTests.cs` file. This includes changes in the way mocks are created, set up, and how return values are specified for mocked methods and properties.

Additionally, a new `TestHttpMessageHandler` class has been added to `SessionManagerTests.cs` to mock the behavior of an `HttpClient`. The `GetHttpClient` method has been updated to use this new class, aligning with the switch from `Moq` to `NSubstitute`.
