Fix cross-references showing duplicate tooltips

Cross-reference links were showing both their own CSS tooltip and the
JavaScript verse tooltip simultaneously, creating a cluttered experience.

Changes:
- Added .cross-references-section class to cross-references container
- Updated JavaScript to skip all links inside .cross-references-section
- Cross-ref links now only show their own CSS-based tooltip

This ensures cross-references show only one tooltip with the verse
preview, not multiple overlapping tooltips.
