The settings main page exists from startup inside the closed dialog and
its IP timer always ran: networkInfo() spawns nmcli twice synchronously on
the GUI thread (~200 ms), stalling every animation. Poll only while the
page is visible. Also write the qt.alive heartbeat without QSaveFile's
fsync (bt-update only checks its mtime).
