Bug 34381: Correct inconsistencies in Authorized values page title

This patch rewords the authorized values template title logic so that it
matches the breadcrumb navigation for consistency.

To test, apply the patch and go to Administration -> Authorized values.

Test all versions of the page to confirm that the breadcrumbs and page
title are consistent with each other:

 - Main view
 - New category
 - View category (click a category, e.g. CCODE, in the main view)
 - Add authorized value
 - Edit authorized value
