Ensure correct selected nav item on broadcast page

Once a broadcast has been submitted for approval it either lives on the
‘Current alerts’ or ‘Previous alerts’ page, depending on where it is
in its lifecycle.

Therefore when clicking into a broadcast from one of those pages the
same navigation item should remain selected.

Because we select the navigation items based on the request endpoint,
this means we need an endpoint for each navigation page, even if the
content of the pages will be the same in both cases.

This commit adds the two new end points, removes the old, single
endpoint and updates links to point to the new endpoint.
