"""Phase C — extend fusion.shipment with dimension fields.

fusion_shipping's native model has `weight` but no length/width/height.
The plating workflow needs all four captured at receiving time so the
shipment record carries everything the carrier API would want. Added
here (not in fusion_shipping) to keep the upstream module untouched.
