Regression: class on page title header for the All Grades page of Gradebook causes font size difference

SAK-22813 applied a styles class ("viewNav) to the header tag used for the page title on the All Grades page. I believe the class is being used to float the header left away from the buttons on the right. But at the same time, it is adjusting the page title's font size, which makes this page inconsistent from the other Gradebook pages.

Make the page title consistent with the other Gradebook pages by either overriding the viewNav class or by restructuring the top of the page.
