fix: 对齐 BasePlatform 新版 SDK 包路径（CI 宿主 m2 快照已晋升）

BasePlatform 2b14e09 服务目录版把 openapi 类挪入子包，CI 复用的宿主 m2 缓存快照已更新为新布局，
旧包路径（openapi.TargetSpec/openapi.client.*/openapi.dto.FlowDto）在 CI 编译失败（run 971）。
本批纯包路径替换，无逻辑改动：
- openapi.TargetSpec/YschOpenCall → openapi.core.*（FlowCenterClient/CmsSiteDirectoryImpl）
- openapi.client.YschBaseOpenApi → openapi.base.*（YschBaseDeptSource/BaseApiController）
- openapi.client.YschFlowOpenApi → openapi.flow.*（FlowCenterClient）
- openapi.dto.FlowDto.FlowSummary → openapi.flow.model.FlowSummary（SvcModels.FlowSummaryVo）
