Bug description

When moving an iOS Live Photo (HEIC + MOV) from Personal Files to a Group Folder, the photo is downgraded to a normal photo.

Only the HEIC file is moved, while the corresponding MOV file is automatically deleted, causing the Live Photo to break.

This issue does not occur when:

• Moving Live Photos within Personal Files
• Moving Live Photos within Group Folders

In those cases, both HEIC and MOV files are preserved and the photo remains a Live Photo.

Steps to reproduce

1. Upload an iOS Live Photo (HEIC + MOV) to Personal Files with ios client
2. Verify it is correctly recognized as a Live Photo
3. Move the photo to a Group Folder
4. Check the files in the destination folder

Expected behavior

• Both HEIC and MOV files should be moved together
• The photo should remain a Live Photo and mov file should be hidden
• No file should be deleted automatically

Additional info

Storage setup (possibly related, not yet verified)

The Nextcloud data directory is located under /data.

• /data is mounted on Block Device A and used as the primary storage
• /data/__groupfolders is mounted on Block Device B and used as separate storage for Group Folders

Start by tracing the move from Personal Files to Group Folders, focusing on the AbortedEventException and the exclusive lock reported for the MOV file. Compare this path with moves within each storage type and verify the behavior with an iOS Live Photo; done means the HEIC and MOV files move together without automatic deletion and the Live Photo remains intact.
