Subject: [PATCH] feat: Add CSS optimization framework with consolidated
 loading

- Added should_use_consolidated_css() method to check for optimization
- Created enqueue_consolidated_css() for single-file CSS loading
- Split enqueue_page_specific_css() for reusable component loading
- Added HVAC_CSS_DEBUG constant support for development
- Maintains backward compatibility with individual file fallback
- Reduces HTTP requests from 20+ CSS files to 1 consolidated file
- Framework ready for consolidated CSS file generation
