Configure logging to output to both console and file

- Added `logging.properties` to resource to include `ConsoleHandler` for console output and `FileHandler` to log messages at INFO level and above to logs/trafficlight.log.
- Ensured the logs directory is created if it does not exist to prevent NoSuchFileException.
- This setup provides persistent logging in trafficlight.log alongside console output for better visibility and tracking.
- Added startup welcome title message in ascii art
