feat: Update file paths for pre-defined users and cache in models and utils

- Update the file path for pre-defined users in `src/models/__init__.py` to use the `ROOT_DIR` variable
- Update the file path for pre-defined users in `src/utils.py` to use the `ROOT_DIR` variable
- Add `ROOT_DIR` variable to `src/models/__init__.py` and `src/utils.py` to store the root directory path
