fix(gui): restart banner says 'Restart required' (process, not container recreate)

The banner said 'Container restart required' and a code comment claimed 'the
container will tear down' — both wrong. /api/restart touches /tmp/meshai_restart,
which the entrypoint watches to restart the BOT PROCESS in place (~seconds); the
container is not recreated. Fix the copy + point users at the existing 'Restart
now' button. Also mention transport connections in the restart-required list.
