Improved Handling of Incremental Invoices for Multiple Cargoes

When dealing with two parcels from the same counterparty, the system separates the invoices until an incremental invoice is created. At this point, the system considers both parcels in the "previously invoiced" section. This approach causes issues when changes are made to only one cargo, as the system reverses all previously invoiced items for the counterparty, including those for other cargoes that were not modified, and then recalculates the overall freight value.
We need the system to maintain separate invoices for each cargo. If changes are made to one cargo, the system should only reverse and recalculate the invoices for that specific cargo, without affecting the invoices for other cargoes associated with the same counterparty.
