Prevent Item Additions During Active Pick/Load Tasks

In Magaya Supply Chain, users are able to add items to a shipment even while pick or load tasks are actively in progress. This can lead to discrepancies between the shipment contents and the tasks executed, resulting in cargo inaccuracies, increased labor costs, and potential shipment errors.
Introduce a system safeguard that prevents users from adding additional items to a shipment when a pick or load task is in progress. This validation ensures that all items intended for shipment are properly accounted for within the associated tasks, maintaining cargo integrity and operational efficiency.
