Add timestamped logging to all console output

- Created logging_utils.py with log_message() function that prefixes all output with date, time, and process name
- Replaced all print() statements with log_message() calls across the entire codebase
- Fixed circular import issues by separating logging from utils.py
- All console output now follows format: [YYYY-MM-DD HH:MM:SS] [process_name] message

This improves debugging and monitoring by providing clear timestamps and process identification for all log messages.
