feat: price home delivery with Jadlog

FREIGHT_ADAPTER=jadlog prices "Receber em casa" through Jadlog's Simulador
de Frete from the order's billed metres and value, adding production days
to Jadlog's delivery time. The package weight is a base plus a weight per
metre from the client, with no default: the adapter refuses to start
without it and without the credentials. The cart re-quotes when the package
changes, and approval quotes again from the server-priced items. The
production stack takes the Jadlog settings, so the read-only probe runs
from the worker's console.
