Implements smart score preservation when switching between 3-arrow and 6-arrow modes:
Core functionality:
- Detects existing scores before allowing arrow count mode changes
- Shows confirmation dialog only when scores exist on scorecard
- Two-option dialog: 'Yes - Keep scores' or 'No - Clear scores'
- User can cancel dialog to abort mode change completely
Score preservation logic:
- Preserves existing scores in their current positions when keeping scores
- Handles 6→3 arrow transition: rows 11-12 become inactive but retain scores
- Maintains visual greying and unselectable state for deactivated cells
- Respects new arrow count limits when copying scores to new structure
Dialog UX improvements:
- Clear messaging explaining the consequences of each choice
- Professional button styling with explicit action descriptions
- Cancellable dialog preserves current state if user changes mind
- Seamless integration with existing toggle switch behavior
Technical implementation:
- _hasAnyScores() helper efficiently detects non-empty scorecard
- _preserveScoresWithNewArrowCount() safely migrates scores to new structure
- Async/await pattern for proper dialog handling and state updates
- Maintains all existing sophisticated end interaction behaviors
This enhancement prevents accidental score loss while allowing flexible
rule switching, matching professional archery scoring conventions.
