fix(stock): allow to create quality inspection after purchase/delivery (backport #55415)

[mergify]

Issue:
The system does not allow users to create a Quality Inspection after enabling "Allow to Make Quality Inspection after Purchase / Delivery" when "Inspection Required before Purchase" is disabled in the Item master.

When the source document is already in the submitted state and post-submission Quality Inspection is allowed, the system should not validate the "Inspection Required before Purchase" setting. Users should be able to create the Quality Inspection regardless of the Item master configuration.
