Bug bash fixes: hash routing + back button, hub-only pages reset on machine switch, exited terminals reap after 10 min, self-update refuses while busy unless forced, touch-sized controls, power confirm by machine name, down interfaces collapsed and empty modules hidden, load label, offline backoff, cron log newest first, procs empty message, timer timestamp parsing
