- Remove plus/minus score controls in GameDetail; tap on score increments by +1
- Keep global Undo control for reversals; maintain keyboard accessibility on score
- No changes to scoring logic beyond UI control removal
- Types: add BreakRule, break metadata to StandardGame, extend NewGameData/steps
- NewGame: add BreakRule and BreakOrder steps with auto-advance
- NewGameScreen: wire new steps into flow
- GameService: set up defaults, persist break order, compute next breaker on +1
- GameDetail: show breaker indicator; treat -1 as undo equivalent
Backfill defaults for existing games via service logic.
