In the dashboard and on the job page, indicate whether the job appears
in the latest jobset eval. That way, the user gets some indication if
a job has accidentally disappeared (e.g. due to an evaluation error).
Currently the dashboard allows users to get a quick overview of the
status of jobs they're interested in, but more will be added,
e.g. viewing all your jobsets or all jobs of which you're a
maintainer.
