Solutions

1. Skip the reorder call when the list is empty
2. Guard persistence of drag-drop order on categories.length > 0

Example fix

// before
await manager.reorderCategories(ids);

// after
if (ids.length > 0) {
  await manager.reorderCategories(ids);
}

if (categoryIds?.length) await manager.reorderCategories(categoryIds);

When it happens

Trigger: Calling reorderCategories([]) or reorderCategories(null), e.g. persisting drag-and-drop order when no categories exist.

Common situations: Empty category list UI saving order on teardown; programmatic reorder with unfiltered id lists.
