Personal usage page does not show settings menu

https://gitpod.io/usage should show the settings menu as well.

ACTUAL	EXPECTED

Currently, the usage page is designed as a full page layout.

Let's keep it full page - this navigation weirdness does not justify redesigning the page.

To maintain discoverability, we could remove it from the settings sidebar, and put it in the main user dropdown at the top instead.
