[Refactor] Replace [SerializeField] + getter with [field: SerializeField] auto-properties

Convert serialized private fields with public arrow getters to
[field: SerializeField] auto-properties across ScriptableObjects
(DieDefinitionSO, CategoryDefinition, ModifierDefinition, Effect,
ModifierBehavior, SumOfValueCategory) and select MonoBehaviours
(DiceRoller, Dice.Entry struct). Fields with type-changing getters
(List→IReadOnlyList) or computed getters are intentionally kept as-is.
