Add clean monitoring and production data collection scripts
- Introduced `monitor_clean.py` for monitoring database status with detailed logging and status updates. - Added `production_clean.py` for running OKX data collection with minimal console output and comprehensive logging. - Implemented command-line argument parsing for both scripts to customize monitoring intervals and collection durations. - Enhanced logging capabilities to provide clear insights into data collection and monitoring processes. - Updated documentation to include usage examples and descriptions for the new scripts, ensuring clarity for users.
