Improve error handling and logging in SpotBot position closing

- Added try-catch block around position closing logic to handle potential failures gracefully.
- Enhanced logging to provide detailed warnings when closing a position fails, ensuring the position status remains unchanged for retry on the next cycle.
- Re-threw exceptions for unhandled cases to inform callers of operation failures, improving overall robustness of the SpotBot.
