Simplify the Followed page layout

- Remove the follow-a-tag / follow-a-pool forms; follows happen from tag
  chips (+ on detail views) and the Follow pool button on pool pages, so
  the empty states now point there instead.
- Move the blacklisted-tag cloud to a full-width horizontal panel at the
  bottom of the page.
- Tag and pool card grids cap at two columns so the cover cards are
  bigger.
