QuickGrid+EF Core - Multiple concurrent queries trigger `InvalidOperationException`

[guardrex]

UPDATE (3/6) ... If the PU fixes it entirely internally, we can just close this issue because the content to workaround the problem added by #34882 is versioned to drop out at 10.0.

NOTE: In the QuickGrid article, the section titled Multiple concurrent EF Core queries trigger System.InvalidOperationException has had its <10.0 versioning removed. When fixed the framework, drop it out at 11.0 if no new API is to be discussed or no explicit demo component is described.

Description

Per the original report in dotnet/aspnetcore#58669 ...

• PU issue for .NET 10
• Blazor movie dB tutorial sample issue

Use a cancellation token to prevent concurrent queries. A new request triggers cancellation of the previous one.
