Describe the bug
Some portions of the IQ# kernel use System.Net.WebRequest to make HTTP requests to the Azure Quantum service, but this API has been deprecated and does not properly support cooperative cancellation via CancellationToken values. As a result, a timeout failure internal to WebRequest may not be interruptible, resulting in a hung kernel instance that does not respond to Jupyter interrupt requests.

These APIs should be updated to use the newer HttpClient API and to propagate cancellation tokens through HTTP requests made via this API.
