The search feature is extremely unloved, and had a ton of hardcoded style rules. These didn't work at all in dark mode, and had some ugly behavior even in light mode (user results would only take up a small amount of horizontal space and were inline blocks, causing the next result to wrap adjacent to it). This change simplifies the display somewhat (especially for user results), and makes it so all our styling is based on our ink variables instead of hardcoding colors and sizes. I'd love to do a real revamp of the search UI entirely, but for now this is much more usable, especially in dark mode. Testing Done: Looked at search results that included both users and review requests and saw that everything looked nice in both light and dark modes.
