Clean up headers

Updates headers to match style guide and makes them consistent
throughout pages in the GUI. Removes instances where a header
element existed and a different header style was being applied.
For example, <h2 class="h4">

Tested: Ran GUI locally and verified that headers look consistent
and have the appropriate sizing while using Chrome, Firefox and
Safari.
