feat(health): 添加 erp-health 健康管理模块骨架

新建 erp-health 原生 Rust crate，覆盖设计规格中定义的 5 大业务域：

- 16 个 SeaORM Entity（患者/家属/标签/医生/健康档案/体征/化验单/预约/排班/随访/咨询等）
- 16 表数据库迁移（含索引、外键、默认值、可回滚）
- 40+ API 路由骨架（患者管理/健康数据/预约排班/随访/咨询/医生管理）
- 12 个权限声明（health.patient/health-data/appointment/follow-up/consultation/doctor 各 .list/.manage）
- DTO / Service / Handler / Event 四层架构，Service 使用 todo!() 占位
- erp-server 集成：模块注册 + AppState FromRef 桥接 + 路由挂载

同步更新 CLAUDE.md 项目进度、wiki 知识库、设计规格文档。
