refactor(sdk)!: 适配 SDK 领域分包——流程/班级/用户中心门面切新包

- FlowModels / FlowCenterClient / FlowCenterClientTest：
  openapi.dto.FlowDto → openapi.flow.model.*（按需引入 FlowApplyBody/Result、FlowCallbackRegBody/Result、
  FlowInstance/FlowSummary）；TargetSpec/YschCallProperties/YschOpenCall → openapi.core.*
- ClassService(+IClassService)：切新班级域门面 YschClassOpenApi + clazz.model.SchTea，
  替换原先用 openapi.client.YschBaseOpenApi 直连基址的写法
- ContactsService / NoticeService / UserCenterService：YschBaseOpenApi → openapi.base.*
- application.yml：随服务目录兜底去掉 open.enabled / user-center-url / userclass 三个 legacy 键
  （userclass 已由 PlatformService 枚举兜底 = base-host + /userclass）

验证：clean test 全绿 64 个非 IT 用例（含本次改动的 FlowCenterClientTest 5/5）。
12 个 *IT 在本机因无 MySQL（jdbc:mysql://localhost:3306/bsch_notice_test）在
entityManagerFactory 阶段 Connection refused，属环境性失败，与本次迁移无关。

说明：这批改动是工作区在途内容（适配 SDK 领域分包所必需），不落库则 Notice 无法对
当前 nexus 上的 SDK 构建通过——即"消费方提交态编译不过"的根因。
