fix(session-limit): émettre AgentRateLimited sur le chemin délégué (#7)

Sur le rendez-vous délégué (idea_ask_agent), quand la cible touchait sa
limite de session, l'événement AgentRateLimited n'était pas émis : l'écart
backend documenté (ticket #7/F2) laissait la surface UI sans signal de
limite pour la cible déléguée.

Le service orchestrateur relaie désormais la limite de la cible vers le
service de limite de session, fermant l'écart en cohérence avec le chemin
direct (#30).

Couverture QA (sortie réelle) : orchestrator_service 63 passed,
session_limit_service 15 passed, session_limit_t4 7 passed,
cargo test -p application 0 failed.
