This builds on API changes in #6017 and #6021 to conditionally turn off the
“Run Job” button based on the current token’s capabilities, or the capabilities
of the anonymous policy if no token is present.
If you try to visit the job-run route directly, it redirects to the job list.
As the angle bracket invocation RFC says:
> There is no dedicated syntax for passing an "else" block

Unfortunately, using a contextual component doesn’t help as
the yield inside that component will still result in content
rendering that would show when the source isn’t empty. So
we decided to change the interface so you have to check
whether the source is empty before using it, which aligns with
how list-table works.
This uses ember-page-title to add dynamic page titles throughout the
route hierarchy. When there’s more than one region, the current
current region is added before the final entry of “- Nomad”.
This changes the templates so the element that contains
the search box is always present, instead hiding only
the box itself when there’s nothing to search. Keeping
the empty element lets it take up its flexbox space so
the facets will no longer be in the centre.
