feat(19-ui-integration): przycisk Drukuj, bulk print, kolejka wydruku

- Przycisk "Drukuj" w prepare.php i show.php z AJAX + duplikat protection
- Bulk print z listy zamówień (checkboxy + header action)
- Kolejka wydruku w Ustawienia > Drukowanie (filtr statusu, retry)
- POST /api/print/jobs/bulk endpoint (package_ids + order_ids)
- ensureLabel() auto-download przez ShipmentProviderRegistry
- Apaczka carrier_id = nazwa usługi, kolumna Przewoznik
- Tab persistence (localStorage), label file_exists check
- Fix use statement ApaczkaApiClient, redirect po utworzeniu przesyłki
- Phase 17 (receipt duplicate guard) + Phase 18 (print queue backend) docs
