feat(miniprogram): 实现小程序透析模块 — 患者端查看 + 医护端录入/审阅

审计后续 H1: 补齐小程序端透析功能，对接后端 12 个 API 路由。

新增内容:
- 患者端: 透析记录列表/详情 + 透析处方列表/详情（只读，4 页面）
- 医护端: 透析记录列表/详情/创建 + 处方列表/详情/创建（6 页面）
- Service 层: dialysis.ts（患者端只读）+ doctor/dialysis.ts（医护端 CRUD）
- 集成入口: 医生工作台快捷操作 + 患者"我的"菜单 + 路由注册
- 基础设施: api.delete 扩展支持 data 参数（后端 delete 需要 version）
