The auto-complete menus were pretty much invisible on dark mode, with a

default white text on a hard-coded white background.
We now use the Ink Menu color palette for the menus, giving us a

consistent appearance with other menus.
The standard menu item padding is also used now, giving us a larger hit

area for the auto-complete items and better visual separation. This

allows us to get rid of the mobile-specific styling as well.
The search results menu has also been fixed to be positioned correctly

below the main navigation pane. Positioning changes had broken the

display, causing it to overlap incorrecly.

Tested the search results and review request auto-complete menus in

dark and light mode, and on desktop and mobile.
