Le toast de fin de tâche de fond liée à un rendez-vous inter-agent passe
de « Main -> DevBackend completed » à « Appel Main -> DevBackend terminé »
(idem en échec / annulé), pour nommer explicitement l'appel plutôt qu'un
état brut. Fallback générique conservé quand requester/target sont absents.

Validations obtenues avant commit : tests frontend annoncés verts pour #91.
