Order modification behavior

When POST /api/v4/order/modify is called, the matching engine cancels the original order and creates a replacement, producing two sequential events:
  1. event_id=3 (Finish) — original order cancelled. The id in the payload matches the old order_id.
  2. event_id=1 (New) — replacement order created with a new order_id.
Clients tracking orders by order_id must update the stored value after each modify call. Use client_order_id for stable correlation across modifications.
The private stream returns active orders, including orders using Retail Price Improvement (RPI) mode.
