Fix results overflow and add debug logging for reference badges

CSS Changes:
- Added max-width and overflow handling to .badge-row
- Added word-wrap and overflow protection to .item
- Added overflow-x: hidden to .window-body
- Badges now use white-space: nowrap to prevent text wrapping
- Item titles now break words properly with word-break

JavaScript Changes:
- Added console.log debugging for reference counts
- Logs show whether fields are present and their values
- Helps diagnose why badges aren't appearing

This should fix the overflow issue and help debug badge visibility.
