A name in SERVICES_ALIASES with no matching container (typo or deleted)
produced no `docker ps -a` line, so it silently vanished from the
dashboard instead of showing as a problem. Track which configured names
were seen and append the leftovers as stopped, logging edge-triggered so
a persistent typo doesn't reprint every 2s poll.
Also corrects the kcmonitor container name and refreshes the README
service list.
