Revamp My Badges tab: draggable badge order, scroll areas, and pending carousel

- Extract reusable SortableList/SortableItem components sharing the same
  @dnd-kit pattern used by the sidebar edit view (DRY)
- Replace ChevronUp/ChevronDown reorder buttons with drag-and-drop on
  accepted badges list
- Wrap accepted and created badge sections in ScrollArea (max-h 420px)
- Redesign pending badges as a carousel showing one badge at a time in
  the notification-style BadgeContent presentation (rotating rays, 3D
  tilt), with left/right arrows to navigate the pending queue
