Enhance nested loop functionality in Interview Wizard Modal

- Added support for tracking active loop paths, enabling nested loop navigation.
- Implemented breadcrumb navigation to display loop hierarchy and allow users to navigate back to parent loops.
- Updated rendering logic for nested loops to support fullscreen mode and improved item management with edit, delete, and navigation options.
- Enhanced user experience with context headers showing parent loop item details and improved item editing capabilities.
