Improve leverage setting in TradingEngine with error handling

- Added a check to ensure the trading client is initialized before setting leverage, enhancing robustness.
- Updated logging messages for clarity and consistency in responses.
- Refactored the leverage setting process to directly utilize the client's method, streamlining the code.
