Status code was overcomplex, given how we control the inputs. Now, it
expects a single value, rather than a comma separated list, and if you
give something it doesn't expect it just returns all. Note, it won't
select the correct box - but if you've been manually editing the URL
that's your own problem ¯\_(ツ)_/¯
Also, as this page will only ever be shown from the tour (tutorial),
it doesn't need some non-help things - such as the download csv button
and associated endpoint.
completely mimicks the job status page, and as such, all the code and
templates have been taken from the job page. This page performs
exactly the same as the job page for now
* total, sending, delivered, failed blue boxes (though they'll just
read 0/1 for now.
* download report button (same as with job download, except without job
or row number in file)
* removed references to scheduled
* kept references to help (aka tour/tutorial) as that'll eventually
change over from a job to a one-off too
