fix: carry item-level project to Purchase Receipt GL entries (#56568)

Purchase Receipt stock and asset GL lines used the item row's cost center
but always fell back to the document-level project, unlike Purchase Invoice
which uses the item-level project. add_gl_entry accepted a project argument
but never wrote it to the GL dict, so the inward, Stock Received But Not
Billed, landed cost, divisional loss, sub-contracting and exchange rate
lines dropped the row's project.

Write project into the GL dict and pass project=item.project on the entries
that were missing it, so project behaves like cost center and matches
Purchase Invoice.
