feat: optimize player selection for touch input

- Increases the number of quick-pick buttons from 4 to 10.
- Adds a '...' button that appears when more than 10 players exist in history.
- Clicking '...' opens a scrollable modal listing all past players for easy selection.
- This provides a much faster player selection flow on touch devices.
