The reboot flow used to send the command and then wait for a liveness poll
to see the link drop. A quick reboot behind a port that never goes away
(a USB-UART bridge) was never seen, so the app went on sending commands to
a board mid-restart. Sending the reboot now declares the link down itself:
the session watcher wakes on the announcement, the Device rebooting dialog
takes over, and the first reconnect attempt waits a moment for the board to
actually begin restarting.
