## Problem
We currently have 3 different libraries for drag & drop, two of which
are not actively maintained anymore.
## Solution
Migrate all usage of the two unmaintained libraries to DndKit.
This PR focuses on using DndKit instead of `react-beautiful-dnd` for
table editor columns sorting

## Summary by CodeRabbit
* **Improvements**
* Redesigned column drag handle with clearer grab affordance, hover and
disabled states.
* More reliable column reordering — drag-and-drop behaves consistently,
including edge cases when moving columns.
* Smoother drag interactions and improved visual feedback while moving
columns.
* **Chores**

modern reorder system.
