refactor: Improve configuration file modification robustness and error handling

- Enhanced `modify_or_add_config()` function with more robust file modification approach
- Added temporary file-based modification to prevent partial writes
- Implemented additional file permission and existence checks
- Improved error handling with more granular logging and error conditions
- Ensured clean file modification and temporary file cleanup
