fix: reject the same Material Request item twice in one supplier selection

Browse Source 
Each row was checked against the pending quantity on its own, so a payload that
listed one item under two suppliers passed both checks and ordered the pending
quantity twice. The dialog cannot produce that, a direct call to the endpoint
can.

(cherry picked from commit 99d56cc850)
