Add comprehensive rule to detect and prevent empty CSS style blocks:
- Identify style objects with no properties
- Flag empty style blocks as potential code quality issues
- Provide auto-fix capability to remove empty blocks
- Handle edge cases like comments-only blocks
This rule helps maintain cleaner codebases by eliminating empty style definitions that often result from incomplete refactoring or forgotten implementations, reducing confusion and unnecessary code.
- Fix handling of missing groupOrder configuration
- Refactor negative conditions to positive ones with optional chaining
- Add comprehensive tests to achieve total coverage
