lauadminandClaude Sonnet 5 d13e7ce2b3 Add Nova Poshta tracking: TTN status, COD amount, payment status
Adds NpTrackingClient (Protocol + real/stub impls) and an ARQ worker that
polls Nova Poshta every minute for orders without a receipt, writing
status, net COD amount (Контроль оплати), and payment status onto the
order. Surfaced in the orders table and detail modal. Marks plan stages
3-4 done in README.
