M2 回合制调度：速度/阵营/队伍顺序规则、先制第一轮、4v4 调试入口与调度测试

- BattleRuntime 调度替换为完整规则：速度高优先、同速玩家优先、同阵营同速 PartyOrder 小优先；先制第一轮玩家全先行，第二轮恢复普通排序；RemainingTurnOrder 同步按调度序输出
- TurnBattleComponent 开局行动者为敌人时自动推进，协程等待 UI 监听注册避免先手事件丢失
- 调试入口支持 1v1 / 2v2 / 4v4 与先制开关；新增敌人队伍预设 4005（四普通敌人）
- UI：修复 UIForm 复用导致第二次开战按钮监听丢失；EnemySlots/TurnSlots 改为按数量复用 item，图标同一单位不重复加载
- EditMode 新增 10 个调度用例（共 35 个）：排序规则、先制两轮、重复敌人分别击杀、4v4 创建、死亡移出候选、固定随机序列复现
