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.
