Page for running general httomo workflow doesn't have button in "header/nav bar"

Most pages in tomohub have a button in the "header/nav bar" that provides easy access and also some visual feedback for which page one is on.

However, if navigated to the "Methods" page and one then clicks on the "Run HTTOMO (Workflow Run)" button:

the app redirects to another page, and this page doesn't have a corresponding button in the "header/nav bar":

It would be nice to have a button in the "header/nav bar" that represents this page.

As one piece of necessary info, this page is associated with the `workflow-run` "route", but knowledge of how to do routing in react isn't necessary to fix this.

Start by locating the React routing and header/nav definitions for the `workflow-run` route, then compare the Methods page navigation with the workflow-run page. Done means the workflow-run page has a corresponding header/nav button and provides the expected visual indication of the current page.
