Feature Request: Signal Scheduling in Cornix#608

Hello Cornix Support,

I would like to suggest a new feature for Cornix: the ability to schedule the exact time for sending signals.

This functionality would be very useful for traders who want to prepare signals in advance but send them at a specific moment, for example, to align with certain market conditions or to reach their audience at optimal times.

I believe this feature could improve flexibility and efficiency for signal providers, especially those who manage multiple channels or strategies.

Thank you for considering this suggestion, and I look forward to hearing your thoughts.
