List available shipping lanes
Returns supported origin/destination pairs. Each pair appears once — lanes are
not split by commodity or transport mode, and this response contains **no prices**.
Pass the selected lane `code` as `lane_code` when creating a quote (`POST /v1/parcel_quotes`).
Currently only **China → Nigeria** is supported.
