Before copying, EXAMINE every folder to sum the account's total message count
and emit a 'plan' event; progress events now carry account_total so the UI
shows a real overall bar, percent and ETA (not just per-folder).
- imapx.FolderMessageCount: read-only count of a folder
- orchestrator: plan pass + grandTotal, plan event, account_total in progress
- web: live progress keyed on account total; PLAN log line; overall bar/ETA

- 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
