A live run could only be stopped one account at a time, and stopping it
at all meant losing the queue: the accounts that had not started yet
stayed idle with no record that they were meant to run.
A run now carries a handle holding the context that stops every account
under it plus the reason it was stopped. Pause and cancel take the same
path and differ only in the status left behind — paused accounts are
what Resume re-runs, and the migration journal makes each one continue
where it stopped instead of re-copying. Accounts still queued when the
stop lands get the same status as the interrupted ones, so the whole
remainder is resumable after a pause and cancelled after a cancel.
Database writes keep using the uncancellable context, so statuses and
counters survive the stop.
The scheduler skips paused tasks: auto-starting a full run would defeat
the pause. An operator stopping a run no longer trips the schedule
breaker either — that is for failures, not for intent.

The run-cancel registry is in-memory; a container restart mid-run leaves
accounts/tasks persisted as 'running' with no goroutine, wedging cancel
(not-in-map -> 409) and blocking remove/re-run.
- startup: ResetRunningOnStartup clears stale 'running' -> 'idle' on boot
- cancel handler: when no live goroutine, ClearStuckAccount + ReconcileTaskStatus
reset the stuck account (and its task) instead of returning 409

- orchestrator: per-account cancellable context registry + CancelAccount;
on cancel, close IMAP connections to unblock in-flight FETCH; account ends
in 'cancelled' status with a cancelled event
- imapx: CopyDeps.OnFolder callback fires after EXAMINE with the folder's
message count (before the long fetch) for visibility
- httpapi: POST /tasks/{id}/accounts/{accountId}/cancel
- web: per-row cancel button while running, folder event shows N messages,
cancelled/done_with_errors status badges
