Cross-category drops worked (previous fix) but had no live preview — the item stayed rendered in its original group the whole time you were dragging over a different one, since dnd-kit only computes a transform for items actually present in a group's array. Added the standard multi-container dnd-kit pattern: onDragOver moves the item into the target group locally as soon as you drag over it (pure preview, nothing persisted yet); onDragEnd finalizes the exact position and only fires a network request for whatever actually changed — order within the final group, and the aisle itself only if it differs from what it was when the drag started. Also handles dropping outside any group: the local preview move is reverted instead of silently leaving an unpersisted, visually-wrong position until refresh.
