Enhanced VerseRenderer with highlight background color visualization:
- Added COLOR_MAP constant with rgba colors for yellow, orange, pink, blue
- Imported HighlightColor type from @/types
- Added hoveredVerseNum state for tracking verse hover state
- Updated verse rendering span with:
- Dynamic backgroundColor based on verse.highlight.color
- Padding and borderRadius for visual polish
- Smooth transitions for better UX
- Proper hover state management
This prepares the UI for highlight data integration in Task 6.
