# Change: Add persistent drag-and-drop sorting (folders + bookmarks)

## Why
Users need to reorder folders and bookmarks via drag-and-drop (including mobile/touch) and have that order persist across reloads. Current HTML5 drag/drop is unreliable on mobile and ordering is not stored for bookmarks.

## What Changes
- Add persistent ordering for bookmarks (new DB column and API endpoint to reorder within a folder).
- Use a touch-friendly drag-and-drop implementation in the web UI for:
  - Reordering folders within the same parent.
  - Reordering bookmarks within the same folder.
- Keep the root group (no folder) as a first-class group in the UI.

## Impact
- Affected specs: API (OpenAPI-backed)
- Affected code:
  - Server: migrations, bookmarks routes, admin routes, row DTO mapping
  - Web: MyPage and AdminPage UI ordering and drag/drop
  - OpenAPI: Bookmark schema and reorder endpoint
