Safety screens: followers, blocking, reporting, admin

Web and mobile:
- Follower/following lists (tap the counts), with Follow buttons and
  "Remove" on your own followers.
- Profile ⋯ menu: block (with confirmation) / unblock, and report with a
  reason and optional note. "Follows you" label, "Follow back", and a
  banner on profiles you've blocked.
- Blocked accounts list in Settings, with unblock.
Web only: /admin for the admin account: stats, open/resolved reports,
resolve, suspend/unsuspend.
