feat(dialysis): 激活 erp-dialysis 独立模块 — 注册到 erp-server

- workspace Cargo.toml 添加 erp-dialysis 依赖声明
- erp-server 注册 DialysisModule 并挂载透析路由
- 修复权限码：health.health-data.* → health.dialysis.list/manage
- 集成测试迁移：erp_health → erp_dialysis import + DialysisState
- TestApp 新增 dialysis_state() 方法
- cargo check 通过，erp-dialysis 10 个单元测试全部通过
