The "next send" time on a campaign is never stale

Every queued email carries a scheduled time, spread evenly across the day's sending window rather than fired all at once. That number is what you see when you check a campaign's progress.

Under specific timing conditions (a campaign resuming after a pause, or a backlog building up faster than the window could clear it), that stored time could end up in the past by the time you looked at it, reading as "this should have sent already" when it hadn't actually been skipped.

The scheduler now recalculates that time on every check instead of trusting a number written once and never revisited, so what you see is always where the email actually stands, not where it stood several checks ago.
