Reorganize RequestBreakdown components into dedicated directory

Move RequestBreakdown.tsx and module CSS into RequestBreakdown/ directory:
- RequestBreakdown.tsx → RequestBreakdown/index.tsx
- RequestBreakdown.module.css → RequestBreakdown/RequestBreakdown.module.css
- Update all import paths to work with new directory structure
- Maintain existing functionality with cleaner organization

All RequestBreakdown-related components now co-located for better maintainability.
