Event admin view does not include 'user-tools' like other admin templates

One-sentence description

Event admin view does not include 'user-tools' like other admin templates

Current behaviour / Reproducing the bug

Check an event admin details page. It does not contain the 'Welcome user, view website, change password, log out' user tools that all other admin pages do contain.

Expected behaviour

Correctly extend the templates, so it is similar to the other admin views
