Dispatches a WebSocket message with cross-stream deduplication.

For orders with a tracked identity (submitted through this client), produces proper order events (OrderAccepted, OrderCanceled, OrderFilled, etc.). For untracked orders (external or pre-existing), falls back to execution reports for downstream reconciliation.
