refactor(dialysis): 透析模块拆分为独立 erp-dialysis crate

- 创建 erp-dialysis crate（DialysisState + DialysisError + DialysisModule）
- 迁移 2 Entity + 2 Service + 2 Handler + 2 DTO 共 8 个文件
- Entity 移除跨 crate patient Relation（FK 列保留）
- Service 内联 validation 逻辑，移除 patient 存在性检查（FK 约束保证）
- erp-health 的 stats/consultation 中 dialysis 查询改为 raw SQL
- ReviewLabReportReq 从 dialysis_dto 移至 health_data_dto（正确归属）
- workspace 全量编译通过
