SQLAlchemy couldn't resolve the string 'Site' in ManagerAccount's
relationship() at query time because Site wasn't guaranteed to be
imported first. Adding the explicit import ensures the mapper is
configured correctly regardless of import order.

Adds three new tables created automatically by create_all on next
startup, plus an additive migration for an existing table:
models/menu_snapshot.py (NEW)
- menu_snapshots: one row per site, holds the full serialized
category+product JSON; upserted on each sync from local_backend
models/online_order.py (NEW)
- online_orders: full order lifecycle from customer submission
through delivery; tracks sync state so local_backend can poll
for unprocessed orders (synced_to_local=0)
models/manager_account.py (NEW)
- manager_accounts + manager_site_access (M2M join table): remote
manager login accounts with per-site access control
models/site.py (MODIFIED)
- order_counter column added; incremented atomically when each
online order is created to generate "ORD-XXXX" public_ref values
main.py (MODIFIED)
- imports all three new models so create_all registers their tables
- _run_migrations() added (same pattern as local_backend) for the
additive order_counter column on the existing sites table
