User journey audit issue

https://github.com/sourcegraph/sourcegraph/issues/34114

Problem description

If you navigate to user settings on a mobile device, it is always shown. Meaning that instead of showing the content of the page - we are taking more than half of the screen by the menu and the user needs to scroll horizontally to reach the content.

Expected behavior

Show the menu as a dropdown with a hamburger trigger button, similar to how all the other websites in the world handle large menus on mobile devices.
