feat 🥁: add no-empty-style-blocks rule

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.
