When an account is added to a sequence with a 0-day wait step scheduled for a specific time (e.g., 10:00 AM), and the account is added after that time has already passed, the system appears to send the email to the outbox before the day ends — rather than at the intended send time. This results in emails landing in the Outbox at unexpected hours.

Request: Update the scheduling logic so that when a 0-day wait step's target time has already passed on the day the account is added, the system schedules the send for the next instance that time occurs — but no longer than 24 hours in the future. This would align with client expectations that the email sends at the configured time, not on the same day it was added to the sequence.
