e4395713 - Fix cancelled HTTP requests showing as Pending in DevTools Network tab (#9685)

Fix cancelled HTTP requests showing as Pending in DevTools Network tab (#9685) ## Description This PR fixes an issue where cancelled HTTP requests appear as "Pending" in the DevTools Network tab. When a request is aborted (for example using `HttpClientRequest.abort` or Dio cancellation), DevTools keeps the request in a Pending state because no response is received. This change detects such cases and displays the request status as "Cancelled" instead. ### Changes - Detect cancelled/aborted requests in `HttpRequestData` - Display "Cancelled" instead of "Pending" in the Network table - Ensure cancelled requests are no longer treated as `inProgress` - Prevent duration from remaining `null` for cancelled requests - Add a regression test to verify the behavior - Update `CustomPointerScrollView` to use `cacheExtent` so the project compiles with the current Flutter SDK All existing network tests pass locally.
