feat(settings): drag-to-reorder dashboard widgets with @dnd-kit

The dashboard layout section already let users reorder widgets via ↑/↓
arrow buttons; the v1.4.43 QoL audit (M1) flagged that modern parity
with Apple Health and Withings web expects drag-to-reorder as the
mouse/touch surface. Adds a GripVertical drag handle on each row wired
to @dnd-kit/sortable. The keyboard fallback stays — arrow buttons are
unchanged and the new handle is also keyboard-operable via dnd-kit's
KeyboardSensor (Tab + Space + arrows).

Both surfaces persist through the same draft → PUT path the arrow
buttons already used, so save / cancel / reset semantics carry over
without changes. Pure reorder logic is extracted into a shared
`reorderWidgets` helper so the mutation payload contract is pinned by
unit tests without spinning up a DndContext.

Bundle delta: ~29 KB gzipped (core 22 + sortable 5 + utilities 2),
well within the 50 KB budget called out in the audit.

All six locales gain `dragHandle` (button label) and `dragHandleHint`
(shared `aria-describedby` paragraph) keys.
