fix(settings): drag-reorder tracks live position; grip becomes a single dot

Two drag issues from user testing:
1. Only adjacent swaps worked - the drag gesture could not move an
   item past multiple positions. Root cause: the pointerInput closure
   kept the index captured at composition; after the live swap
   (items.add(target, removeAt(index))) the closure's index was
   stale, so subsequent targets were computed from the wrong origin
   and the saved order got corrupted (also made previously moved
   items snap back).
   Fix: track the dragged item's live position via draggingIndex -
   onDragStart resolves it with items.indexOf(screen), onDrag computes
   the target from draggingIndex and updates it after each swap.
2. The six-dot grip icon was ugly; replaced with a single 8dp themed
   dot (Box + CircleShape inside the 48dp touch area, onSurfaceVariant
   color). ic_drag.xml removed.

What's-new rewritten in en/zh/tr with ONLY this release's changes
(user rule: replace, never append history). Version stays 4.4.9
(覆盖 per user). Verified: settings + app compile, check_strings.py
clean.
