SSE: не рассылать ratings на правки без влияния на рейтинг; событие group при смене настроек группы

- notify.match_changed получил флаг ratings: фото (игрок и админ) его не шлют, правка
  партии — только если изменились входы рейтинга (match_service.rating_inputs до/после).
- PATCH /api/groups/{id} публикует group — переименование и правило 9 раундов видны
  остальным участникам сразу.
