Admin ring on comments/channel + pending-submissions dots on Admin tab & Submissions subtab

- adminBadge.js: add applyAdminRing(el, id) for surfaces that already place the
  star on a specific element and just need the ring.
- comments: ring + star on admin authors' avatars; round the comment avatar box
  so the ring reads as a circle.
- channel page: ring the inner rounded avatar box (star already on the wrap).
- Notification dots: red dot on the profile modal's Admin nav tab and on the
  Submissions subtab button when there are pending submissions, so admins know
  where to look. profileModalController.setSubmissionsUnreadIndicator toggles
  both (Admin nav dot gated on the tab being visible); driven from
  applyProfileNotificationDot off app._submissionsPending.
