[Refactor] Replace hardcoded categories with data-driven SO system and abstract dice

- Add abstract dice system (IDie interface, DieDefinitionSO, StandardDieSO, DieInstance)
  to support future custom dice types while keeping backward compat via int[] DiceValues
- Replace YachtCategory enum and CategoryScorer switch with CategoryDefinitionSO hierarchy:
  SumOfValueCategorySO, NOfAKindCategorySO, FullHouseCategorySO, StraightCategorySO, SumAllCategorySO
- Add CategoryCatalogSO for ordered category collections and DiceCheckUtility for shared logic
- Refactor ScoringSystem, Views, GameManager, GameController to use SO references
- Update CategoryCondition modifier to use SO reference instead of enum
- Update all editor tests to use SO-based categories and DieInstance
