The REST framework resolves _order_by parameters and embed prefetches by
walking prefetch_whitelist, which is built from DBIC relationship names.
The auto-generated relationships use the FK column names (itemnumber,
frombranch, tobranch), but the API exposes them as item, from_library,
and to_library. Sorting by item.biblio.title etc. threw a 500 because
those names were not in the whitelist.
Adding belongs_to aliases below the DO NOT MODIFY line bridges the API
names to the DBIC names, matching the convention used by other Koha
schema result classes (e.g. Koha::Schema::Result::Item).
Also updates the relation methods in Koha::Item::Transfer to use the new
aliases consistently, so the accessor names line up across both layers.
