atsunatsu 5f1eb239ed feat(lotw): cancel in-flight sync, honest progress bar, drop stale hint
- Cancel: the dialog's cancel/back while syncing now aborts the download job
  (cooperative cancellation in the stream reader, CancellationException
  propagated, nothing written to storage). An accidental full sync can be
  stopped immediately.
- Progress: the size estimate is conservative (900 B/record vs measured 720)
  so the bar never hits 100% before the download truly ends; storage writes
  moved to the IO dispatcher (multi-MB per-grid QSO JSON used to freeze the
  main thread after download); when the bar caps, the UI switches to
  'Processing downloaded data…' instead of looking stuck.
- Removed the outdated '3-10 seconds' hint (misleading for large accounts).
