feat: 基金管理人取数支持跨环境库名——新增 DbSchema 库名插值，bigdata 连接串指向 96/glms_bigdata

问题：SQL 硬编码物理库名（bigdata./glms_bigdata.），关联库在不同环境库名不同，换环境即失效；且仓库所有 appsettings 均未配 bigdata 连接串，本地/单测环境一直走 Unavailable 降级。 - 新增 YLErpDAL/DataBase/DbSchema：从连接串 database= 解析物理库名（含反引号、\w+ 白名单校验、进程级缓存），跨库 SQL 写 DbSchema.Of("bigdata").mf_fundarchives ——代码只认逻辑连接名（等价 Java @Mapper 指定数据源），物理库名归各环境 appsettings；将来 join ERP 主库用 DbSchema.Of("ylcms") 同法插值 - FundManagerLookupService：SQL 两处库名前缀改为插值（查找逻辑/CONVERT/COLLATE 不变），Unavailable 降级语义不变 - appsettings.local.json / UnitTestProject appsettings.json 补 bigdata=192.168.2.96:3306/glms_bigdata（抄现有 96 库连接串改库名） - 新增 FundManagerLookupServiceTest（连 96 实库）：DbSchema 解析断言 + Lookup 连通性实测 511160.SH → Unique「东财基金管理有限公司」全链路打通；161210/630006 因 mf_investadvisoroutline 仅2行无映射返回 NotFound（数据覆盖问题）
