Payload for the scheduled-signal-open broker event.

Emitted automatically via scheduleEventSubject (action "scheduled") when a new scheduled signal is created and starts waiting for priceOpen activation. Forwarded to the registered IBroker adapter via onSignalScheduleOpen. The scheduled -> active transition is NOT reported here — activation arrives through onSignalOpenCommit.
