fix: Enhance logging configuration handling

- Updated logging setup to use default values when the [Logging] section is missing, ensuring consistent behavior.
- Improved handling of colored output and log file configuration based on the presence of the [Logging] section across multiple modules.
- Refactored related code in core and service plugins for better clarity and maintainability.
