Track market orders to prevent unknown order warnings and update UI

[Copilot]

Market orders placed after limit order timeout were not being tracked, causing websocket updates to log warnings for "unknown orders" and preventing the UI from showing final fill status.

Changes

Modified order tracking logic (HyperliquidBroker.cs):

• Removed IsCompleted() check from AddOrderTracker() to allow tracking already-filled orders
• Added tracker registration for market orders created during timeout processing

Market orders fill immediately and have terminal status upon creation, but still receive websocket updates that need to be matched for UI updates and proper lifecycle management.

// Before: Skipped completed orders
if (!result.Success || result.Order == null || result.Order.IsCompleted())
    return;

// After: Track all successful orders including market orders
if (!result.Success || result.Order == null)
    return;

// In timeout processing, after placing market order
if (marketTradeResult.Success && marketTradeResult.Order != null)
{
    // Track the market order to handle websocket updates
    orderTrackers.TryAdd(orderId, new OrderTracker(...));
    updateChannel.Writer.TryWrite(new OrderUpdate(...));
}

This ensures websocket updates are matched to trackers, allowing the UI to display correct order status before exit.

This section details on the original issue you should resolve

<issue_title>Fix Log Warnings For Market Orders</issue_title>
<issue_description>Currently market orders are not tracked in the app, which has two consequences:

1. we get a bunch of warnings in the logs (see below)
2. the app exits without showing that the orders actually successfully filled (or not)

We should change this so that market orders are tracked and status updates returned to the client code in Program, so that the screen can be updated and the app shows the correct order status before exiting.
