fix: rating not shown after refresh, comment reactions not shown until clicked

- The interactive RatingStars widget was always initialized with
  initialScore={0}, ignoring the current user's existing rating.
  Fetch it via a third parallel query and pass it through — the
  rating was persisted correctly all along, just never displayed
  back.
- CommentReactions never fetched its counts on mount, relying solely
  on initialCounts/initialUserReactions props that comments-section
  always passed as empty — so every comment showed zero reactions
  until you clicked one yourself (which returns fresh counts from the
  POST response). Fetch on mount via the existing GET endpoint.
