Fix score-based ordering in suitbuilder frontend

Updated JavaScript to maintain score ordering during streaming search:
- Replace addSuitToResults() with insertSuitInScoreOrder()
- Add regenerateResultsDisplay() to maintain proper DOM ordering
- Medal assignment (🥇🥈🥉) now based on score ranking, not arrival order
- Suits with highest scores now always appear at top during live search
- Updated displaySuitResults() to sort by score before displaying
