feat(pos): wire POS v2 to live data (board, orders, payments)

POS v2 is now a real, working point of sale at /[locale]/pos2 (was a static
mock). It reuses the existing data layer so it shares the React Query cache and
offline pipeline with the classic POS:

- Table board ← fetchCafeTableBoard (Free/Busy/Reserved/Cleaning, live totals,
  guest-QR badge); polls every 15s. Open a free table to start an order; open a
  busy table to hydrate its existing order (GET order → cart hydrateFromOrder).
- Order screen ← real branch/café menu + categories, bound to useCartStore
  (add/qty/remove). Send via submitOrderToApi (online + offline outbox) then
  re-hydrate; "ارسال (n)" shows the pending (unsynced) line count.
- Pay sheet ← POST /orders/{id}/payments. Cash (numpad + change), Card, and a
  Split helper (records the full amount; split is cashier guidance for now).
- Online/offline badge, loading/empty states, toasts, busy overlay, and a
  "نسخه کلاسیک" link back to /pos.

The static design mock stays at /[locale]/pos2-preview (dev-only, 404 in prod).
