Change secret code to PIN system with explainer text

- Renamed 'secret code' to 'PIN' throughout UI
- Added PIN explainer text explaining how system identifies players
- New players get random 6-char PIN, must save it
- Players use name + PIN to update scores
- PIN ensures unique identification for each player
