refactor 6:

- CombatInfoFormUseCase.cs 改成回调驱动：
    - 不再直接读 GameEntry.CombatNode
    - 由 CombatLoadSession.cs 在打开 CombatInfoForm 前注入 modelProvider 和 TryEndCombat 回调
- CombatSelectFormUseCase.cs 的默认 coin provider 改成返回 0，不再偷偷 fallback 到 GameEntry.CombatNode
- CombatFinishFormUseCase.cs 去掉了未准备 summary 时对 GameEntry.CombatNode 的兜底读取
- MapData.cs 进一步补充了战斗初始快照：
    - InventorySnapshot
    - ParticipantTowerSnapshot
- CombatLoadingState.cs 现在会把这些背包/参战塔快照也一起打进 MapData
- MapEntity.cs 配置建塔面板时不再直接读 PlayerInventory，改为用 MapData 里的快照
