fix(badge): refresh the OS unread badge on block/unblock

The unread sum already excludes blocked chats, but nothing recounted on
the flip — the dock badge/overlay kept the blocked chat's unreads until
the next unrelated message event. Block drops them immediately; unblock
restores them, matching the mute toggle's existing pattern.
