fix: check-status.py smooth in-place redraw, remove comment bars

- Use \033[H\033[J (home + clear-to-end) instead of just \033[H to
  prevent stale lines from previous frames persisting when output
  shrinks between refreshes.
- Fix cursor restore on exit: was \033[?25l (hide) instead of
  \033[?25h (show), leaving terminal with invisible cursor.
