Subject: [PATCH 1/2] feat: implement structured JSON error logging

- Add python-json-logger dependency.
- Configure file handler to use JsonFormatter for structured logging.
- Keep console handler with the existing text format.
- Refactor log_and_format_error to log a dictionary with structured error data.
