fix: GetOutCard 集成 — bot 出牌类型不再硬编码 DanZhang

根因: MakePlay 永远设 Type=DanZhang，bot 路径跳过 GetOutCard 校验，
导致多牌组合（对子/顺子等）被错误标为单张。

修复:
- MakePlay: Type=DanZhang → Type=None（占位，等引擎赋值）
- WaitWanJiaShuRu case4: bot 有Ids时通过 GetOutCard 获取正确牌型
- payCard.Pos 补设（GetOutCard 输出 Pos 默认为0）
- ISMCTS 日志: 按 Ids 为空判断 pass，而非 Type

现在游戏日志正确显示: type:DanZhang/type:None/type:DuiZi 等
