Standardize breadcrumbs on interlinear page

Update interlinear page breadcrumbs to match site-wide styling:
- Use standard .breadcrumb class instead of .breadcrumbs
- Use CSS variables (--link-color, --text-secondary) instead of hardcoded colors
- Change separator from / to > to match other pages
- Add border-bottom and proper spacing
- Remove inline styles
- Apply consistent dark mode styling

Breadcrumbs now match the refined navigation style used throughout
the rest of the site.
