Search field_numero_facture too in the entrée-liée autocomplete

Several entrées for the same client often share the same title format
("EPAU - 2026-01-05"), so being able to type the invoice number itself
is what actually finds the right one quickly. buildEntityQuery()
withholds $match from the parent call (which would otherwise add its
own title-only condition) and applies it manually as an OR across title
and field_numero_facture instead.

Verified live: searching "F2549" (not present in the title at all, only
in field_numero_facture) now correctly surfaces that entrée; a
title-only search and a no-match search both still behave as before.
