feat(108): delivery status management

Phase 108 complete (v3.2 milestone):

Plan 108-01 — Delivery Status DB & CRUD:
- Tabela delivery_statuses z seedem 11 statusow systemowych
- DeliveryStatusRepository (CRUD + per-request static cache)
- DeliveryStatus::setRepository() — DB fallback dla static final class
- Panel /settings/delivery-statuses (zakladki Statusy + Mapowanie)
- Sidebar przebudowany: Statusy zamowien + Statusy przesylek

Plan 108-02 — Automation Dropdowns z DB + UI Refactor:
- Dropdowny automatyzacji ladowane z DB (warunek shipment_status + akcja update_shipment_status)
- Walidacja przez DeliveryStatus::getAllStatuses()
- Osobna podstrona formularza CRUD (delivery-status-form.php)
- Lista uproszczona: rename Terminal -> Koncowy, usunieta kolumna Typ
- BREAKING: drop backward compat dla starych grupowych kluczy automatyzacji
- Bug fix: path params w DeliveryStatusesController via \$request->input('id')
