Lists every wagon allocated to a booking with tare, equated length, capacity, container and seal numbers, plus footer totals and signature lines. Issued on cargo acceptance (export) and on allocation before marshalling (import), so the endpoint rejects bookings with no wagon allocations. Price per wagon splits the booking amount by allocated weight, with the last row absorbing rounding so the column sums to the total. Reuses the existing marshalling document renderer and its Chromium-less tabular fallback.
