Remove obsolete configuration management and test settings files

- Deleted the `config.py` file responsible for managing bot configuration via environment variables and `.env` files, as it is no longer needed.
- Removed the `test_settings.ini` file used for testing, which contained mock configuration data.
- Cleaned up the project structure by eliminating unused files to enhance maintainability.
