Link the user show page from the admin users index

The admin users index only exposed Edit / Delete actions per row, so
the Accessible-applications panel on the user show page was unreachable
without typing the URL by hand. Adds a View action and turns the email
into a link to the show page — mirroring how the applications and
groups indexes already work.
