Feature request: Real-time order status updates via WebSocket (order lifecycle events + fills)

[shoebshah64]

I’d like to request a new feature: native real-time order status updates via WebSocket in OpenAlgo. This feature would push order lifecycle events (open, partially_filled, filled, canceled, rejected, replaced, updated, completed) to clients over the existing WebSocket channel (or a new dedicated channel) so strategies can respond immediately to order changes without polling the orderbook API.

Avoids polling the orderbook repeatedly (reduces rate limits, latency and CPU waste).

Ensures strategies can immediately place SL/TP, bracket orders or manage risk the instant an order fills or is canceled.

Enables coordinated multi-leg flows where the next step must execute promptly after a fill.
