CLAUDE: Enhance baserunner panel with lead runner auto-select and clickable catcher

- Swap base order to 3B, 2B, 1B (left to right, closer to baseball diamond)
- Auto-select lead runner on mount (priority: 3B > 2B > 1B)
- Make catcher pill clickable to show catcher card only
- Add 'catcher' as a selection option alongside runner bases
- Update expanded view to handle catcher-only display (centered, single card)
- Add toggleCatcher() function
- Update tests for new base order and auto-selection behavior

All 15 RunnersOnBase tests passing
All 16 RunnerCard tests passing
