UX: spacing adjustments, mobile nav refactor (PR #13874)

On desktop I’ve adjusted the spacing a bit, and moved the tracking & new message buttons outside of the vertical ul, this matches what other user pages do and spaces things out a little more. I also fixed an issue where the tracking dropdown was cropped due to overflow being hidden.

The tracking nav on mobile wasn’t working in the dropdown, so I tried to restructure things in a reasonable way to avoid it… also trying to make tags visible because I know some admins use them a lot (the mobile user nav could probably use a total redesign soon… there’s a lot going on).

Minor but another place where we could use one {{#if (and site.mobileView showNewPm)}}
