fix: resolve CI linting issues and add missing newlines

- Fix all line length issues (120 character limit)
- Remove all trailing whitespace
- Add missing newlines at end of files
- Add CLICKZETTA_VOLUME_DIFY_PREFIX environment variable to docker-compose.yaml
- Ensure proper code formatting for all ClickZetta files
