notifications P1: лента с действиями + «Скрыть все»

- NotificationsRepository: парс actions[] (label/link/type/primary),
  dismissAll (DELETE /api/v2/notifications), executeAction (GET/POST/PUT/DELETE по action.link)
- F7NotificationRow: FlowRow кнопок-действий (primary=заливка, прочие=контур)
- NotificationsSheet: заголовок «Уведомления» + «Скрыть все», проброс действий,
  оптимистичное скрытие после действия/скрыть-все

Контракты сверены с исходником notifications на forbion (deleteAllNotifications, actionToArray).
