📝 Walkthrough

Walkthrough

This change introduces six new tests in the ProductImageActionHandlerTests suite. The added test methods verify the behavior of media uploads when a background upload feature flag is enabled. They assess scenarios for successful and unsuccessful uploads, ensure that UIImage uploads correctly pass a filename and alt text, update the uploading status accurately, handle the discard of an upload, and propagate product ID updates to existing statuses.
