Requisitions with IN_APPROVAL state must display the "approved quantity" and "remarks" column and allow editing them, similar to the authorized state. When doing this, please ensure that there's a common way to check if requisition is during approval and that this is checked in all places, rather than manually checking for status.
Approved quantity and remarks columns are visible if requisition is IN_APPROVAL
Approved quantity and remarks columns are editable if requisition is IN_APPROVAL
The product grid behaves the same way as for authorized state for requisitions IN_APPROVAL
