Describe the Bug

When files are transferred from one user to another user via transfer ownership, only the classification results are transferred, face detections are lost. Also, the transferred files are not added to the face detection queue for detecting the faces again.

Expected Behavior

Either keep the face recognition and run the clustering for the new user or re-run both face recognition and clustering after moving the files.

To Reproduce

• Upload images to one user
• let recognize do its thing
• transfer ownership of these images to another user
• see that face detections are lost and files are not added to face detection queue

Debug log

No response

Start by tracing how transfer ownership moves files between users and how face detections and the face-detection queue are handled afterward. Reproduce the transfer with recognized images, then verify that face detections are preserved or that both face recognition and clustering are queued for the new owner.
