fix: resolve all YAML linting errors in playbooks and inventories

- Fix line length violations by using YAML folded strings (>-)
- Remove trailing whitespace from all files
- Add missing document start markers (---) to inventory files
- Improve readability of long Jinja2 template expressions
- Maintain YAML linting compliance for production-ready code

All files now pass yamllint validation successfully.
