Indicate template on scheduled jobs

We’ve removed the template on the jobs page, so you can no longer see
which template a job is about to be sent with.

This is removing information which might enable you to undo a costly
mistake.

I don’t think we need to bring back the whole template – giving its
name, and a link to it meets the need just as well.
