feat: 增强开奖与设置控制器的币种支持功能

引入 CurrencyResolver，用于在 DrawCurrentController、DrawResultShowController 与 DrawResultsIndexController 中统一处理币种代码解析。
更新 DrawHallSnapshotBuilder 与 DrawResultViewService 的构建方法，新增币种代码参数支持，确保开奖相关功能中的币种处理一致性。
增强 SettingIndexController：新增允许访问的 KV 配置分组校验。
在 OddsStreamService、PlayConfigStreamService 与 RiskCapStreamService 中新增广播功能，用于在玩法目录变更时推送更新通知。
新增测试用例，验证风险限额发布的广播行为。
