panel: Show warning indicator when unsafe-mode is on

MetaContext added an unsafe-mode property, which we will use to restrict
a number of privileged operations unless it is enabled. It is meant to
only be enabled temporarily for development/debugging purposes, so add
a scary icon to the top bar as a reminder to turn it off again.
