Target that owns the multi-participant route, e.g., the shared lever actor.
This interaction identifier (FInteractionRuntimeTargetId) belongs to FInteractionRuntimeMultiParticipantRouteEvent under InteractionRuntime|MultiParticipant.
Blueprint or editor workflows can write this value when constructing, overriding, or customizing the owning object.
Keep identifier values stable once content ships because saved state, prompt routing, and authored references may depend on them.
