fix: prevent endlos games from ending immediately on first score

- Change endlos raceTo from 0 to Infinity to prevent automatic completion
- Update NewGame component to handle Infinity values properly
- Add Infinity checks in game completion and winner logic
- Fix game progress calculation for endless games

Fixes issue where selecting 'endlos' mode would end the match
immediately when any player scored their first point.
