Research direction

Reproduce the issue by enabling auto upload for all files from the past, creating a queue of 24k items, and opening the upload queue. Then trace the upload queue screen and its list handling; done means the phone remains responsive and scrolling is manageable while the large queue is displayed. The payload names no files or tests.
