When showing paid invoices for linking, exclude those whose
payment is already linked to a bank entry (fk_bank > 0).
A paid invoice can only be linked to one bank transaction.

The column in llx_paiementfourn_facturefourn is fk_paiementfourn (no underscore)
not fk_paiement_fourn. This caused payment lookups to fail, creating
duplicate payments instead of linking to existing ones.
