cinny-threads: clear thread notifications on room Mark-as-Read
A room's unread in cinny is the main-timeline notification count plus the
sum of every thread's count (Room.getUnreadNotificationCount sums
threadNotifications), and roomHaveNotification keys off that. The
room-level Mark-as-Read sent a receipt only for the latest non-thread
event, clearing the main timeline but leaving every thread count intact -
so a room with any unread thread stayed bold in the sidebar even after
being marked read, with no per-thread indicator to explain why.
Send an unthreaded read receipt against the room's latest event instead;
the SDK/server treat it as clearing the main timeline and every thread's
unread bucket at once.
