"""Teste regula "exclude de la declarare" (operations_mapping.exclus).

O operatie exclusa nu se declara la RAR: randurile de import cu toate operatiile
excluse devin 'excluded' (Nedeclarat) si nu se comit; operatiile excluse dispar
din panoul de mapare; submission-urile API blocate trec pe needs_data cu motiv.
Un cod ales explicit pe rand bate regula de excludere.
