Unable to reorder columns via drag-and-drop

@Ali @sandra
I am currently unable to reorder markbook columns via drag-and-drop. The UI no longer responds to drag actions, and column positions remain fixed. This functionality was previously working as expected.

Environment:

Gibbon Version: v30.0.01
PHP Version: 8.3.30
MySQL Version: 10.11.16

There are no visible console errors during the interaction.

Has anyone else experienced this issue?

Regards.
