fix(comments): register event listener for typed comment events

Since the typed comment events (CommentAddedEvent, CommentUpdatedEvent,
etc.) were introduced in NC34, dispatchTyped() dispatches using the exact
subclass name. Registering only for CommentsEvent::class means the listener
never fires, so comment mention notifications are never created or cleared.
