Improve logging and error handling with session IDs

Introduces a SESSION_ID variable for log file naming and tracking, updates log file paths to include timestamps and session IDs, and enhances error handling output to use custom message functions when available. Also improves log file management and user guidance for viewing logs, and refactors error handler to better support containerized environments.
