fix(freight): correct direct CAS lines and sync inventory on schedule load

End-to-end testing of the direct truck-to-train flow surfaced two defects
in the carriage acceptance sheet's no-wagon fallback. Container numbers
were read from freight.containers, which only gains rows at allocation,
so a direct booking's declared containers never appeared; they are read
from booking_container_units now, seal numbers included. The weight used
bulkTotalWeightTons alone, which is null for CONTAINER and PER_TON bulk
bookings, printing 0.00 — cargoTotalWeightVgm is the real weight there
and only holds an item count for PER_ITEM break-bulk.

Separately, warehouse cargo can be loaded from the Load-to-Train queue or
from the schedule, but loading from the schedule never advanced
warehouse_inventory. The booking went IN_TRANSIT while its cargo still
read as sitting in the warehouse — the same inconsistency that produced
the spurious dispatch block. loadBooking now moves the inventory to
LOADED in the same transaction, and no-ops for direct bookings.
