Add request tracking ID logging for Tinkoff API calls

- Modified PlaceBuyOrder to log x-tracking-id header from PostOrderAsync
- Modified PlaceSellOrder to log x-tracking-id header from PostOrderAsync
- Modified CancelOrder to log x-tracking-id header from CancelOrderAsync
- Added example demonstrating tracking ID extraction and logging
- Tracking IDs are essential for efficient communication with Tinkoff support
