Subject: [PATCH] Profile stats from microcosm, fix verification badges
 everywhere, drop post count UI

Profile stats:
- hydrateProfile no longer calls the AppView. followersCount from Constellation
  backlinks; followsCount from counting the actor's own graph.follow records.
  postsCount dropped (can't be counted reliably), and the posts metric is removed
  from the profile header UI.

Verification badges:
- hydrateProfileBasic now populates  too, so badges show in feeds,
  threads, lists, search and post authors - not just on the full profile page,
  which is why they looked buggy/inconsistent.
- Verification state is cached per author (5 min TTL, in-flight dedupe) so the
  same author across a feed doesn't re-run the Constellation lookups, and a
  transient failure isn't cached (so a badge isn't suppressed for the whole TTL).
