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
