feat: tablet-first UX overhaul with wizard improvements

- Tablet-first responsive scoreboard: whole player card is tap target
- Per-step wizard backgrounds and live summary panel
- Larger touch targets, safe-area handling, reduced-motion support
- German UI error strings in App.tsx
- Updated SOUL.md and README.md for current architecture
- Cleanup: removed legacy components, .cursor/, UI_IMPROVEMENTS.md
- Renamed package to bscscore, fixed TOTAL_WIZARD_STEPS
