Where do I see when the next sync or push will happen?

The sidebar shows a live countdown (e.g. "Next push in 4m" when push is in Auto). Outside your Active hours it shows "resumes 08:00" (or "resumes Mon 08:00") instead of a countdown, so you can always see why it's quiet. The Scheduling cards also show "last synced — …" and "last pushed — …" timestamps in the top-right of each card, and "Syncing…" / "Pushing…" while one is in progress.
