feat(28-shipment-tracking-ui): badge'e statusow dostawy, linki sledzenia, ustawienia interwalu trackingu

- Kolorowe badge'e statusow dostawy w tabelach paczek (show.php + prepare.php)
- Link sledzenia z carrier detection (InPost, Apaczka, Orlen, Allegro, Google fallback)
- Sekcja Status dostawy w boksie Platnosc i wysylka
- Ustawienie interwalu trackingu crona (5-120 min) w zakladce Ustawienia
- Tekstowe mapowania statusow Apaczka API (NEW, CONFIRMED, etc.)
- Fix: use-statements ApaczkaShipmentService (pre-existing bug)
- Fix: pickup date normalization (next day po 16:00)
- Fix: przycisk Pobierz etykiete (POST zamiast link do prepare)
