irc: fix live updates and preserve default buttons on reopen

- Set  in  so append/refresh repaint.
- Build button rows explicitly (Send + TextViewer defaults) and disable
  automatic default insertion to ensure defaults remain after reinit.

Also clarifies behavior when reopening a keep_running view.
