fix(qconnect): force AskForQueueState resync on QueueTracksAddedFromAutoplay

105 carries only bare queue_item_ids (no track_id/context), unreconstructable
by the reducer; resync pulls the authoritative QueueState so autoplay-grown
tracks become visible. Matches the ShuffleModeSet/Reordered/Removed pattern.
