feat(ui): Add "people" feed

[ashquarky]

Resolves #408

Changes:

• Refactors the purple "nav tabs" view used in a few different places (e.g. New posts/Popular posts on community pages, Posts/Yeahs/Followers/Following on userpage, etc.)
  • CTR's is reimplemented and had its design changed slightly. Fixes numerous janky layout things.
  • Portal's is a port, with the visuals set to match the original without changes (Portal needs its page layout refactored, but that's out of scope for this)
  • Web not changed for now, it's messy but works
  • Key improvement other than jank removal is that the control automatically handles resizing to the number of buttons. This is done with webkit-box (proto-flexbox.)
  • Wrapping is not handled, rows still need to be done by hand in the markup.
  • Can add or remove tabs without breaking the layout. Speaking of new tabs...
• "People" feed view. So:
  • My Feed shows posts from users and communities that you're following
  • People Feed shows posts from users you're following only
  • Global Feed shows posts from the whole site

Happy to stew on branding here, since I don't think "people" actually communicates what this does. "Mutuals" feed is an interesting thought but we don't have a concept of mutuals on Juxt right now.

• I have read and agreed to the Code of Conduct.
• I have read and complied with the contributing guidelines.
• What I'm implementing was an approved issue.
• I have tested all of my changes.

New tabs control for CTR. Note the full width and even sized buttons.

People feed (these are two different accounts so the feeds are different)

Gave it a firefox-based test, all seems to work nicely.

Just one have real comment about the JS side of the new tabs.

I played with doing querySelector(":focus") which could be a solution but. I'm so done with this release cycle yanno
