 * Backfill (Phase 111): zamowienia z payment_status=2 i status_code='nieoplacone'
 * (source=allegro lub shoppro) zostaja przestawione na status 'w_realizacji'.
 * Zmiana idzie przez OrdersRepository::updateOrderStatus, dzieki czemu powstaje
 * wpis w order_status_history i order_activity_log.
 *
 * Naprawia luke z Phase 98 (gate $wasCreated dla order.imported) — zamowienia
 * zaimportowane przed potwierdzeniem platnosci, ktore utknely w 'nieoplacone'
 * mimo opłacenia.
 *
 * Idempotentny: drugie uruchomienie na czystej bazie nie zrobi nic.
 *
 * Flagi:
 *   --dry-run     pokaz tylko liste kandydatow, bez zmian
 *   --use-remote  uzyj DB_HOST_REMOTE zamiast DB_HOST (dla operacji recznych agenta)
