feat(connect): Phase 4 — local backend online order integration

4.1 — cloud_sync.py
  - _push_menu_snapshot(): serializes digital-visible products+categories
    and POSTs to cloud /api/menu/sync every 5 minutes
  - _pull_pending_orders(): polls cloud /api/orders/pending/{site_id}
    every CONNECT_SYNC_INTERVAL_SECONDS (default 30s); creates local
    Order + OrderItem rows, marks synced on cloud, broadcasts SSE event
  - _connect_loop(): second asyncio task running the fast poll loop;
    piggybacked menu push fires every 5 min regardless of poll interval
  - _sync_once(): captures site_numeric_id from heartbeat response and
    stores it in license_state so Connect loops can use it
  - start_cloud_sync(): now creates and returns both tasks

4.2 — orders model/schema/migrations
  - models/order.py: table_id made nullable (online orders have no
    table); 7 new online_* columns added to Order
  - schemas/order.py: OrderOut table_id Optional, all 7 online_* fields
    added
  - main.py: 8 additive ALTER TABLE migrations for orders table

4.3 — routers/connect_orders.py (NEW)
  GET  /api/connect/orders/incoming      — pending online orders (any auth)
  POST /api/connect/orders/{id}/accept   — accept (manager)
  POST /api/connect/orders/{id}/reject   — reject with optional reason (manager)
  POST /api/connect/orders/{id}/status   — progress through lifecycle (manager)
  All state changes mirror to cloud via background task and broadcast SSE

4.4 — main.py router registration
  connect_orders router registered at /api/connect

config.py
  CONNECT_SYNC_INTERVAL_SECONDS setting added (default 30)
