Get HIP-4 L4 orderbook
Get the full L4 (individual order-level) orderbook reconstruction for a HIP-4 outcome side. Returns the latest snapshot if no timestamp is provided. Within each price level, bids and asks are ordered by true queue priority (ALO priority insertions included), not by placement time. Depth truncation is by order count, so the orders at a depth cut can differ from responses served before 2026-07-21.
