fix(health): 数据完整性 + 代码规范修复 — FK约束/版本类型统一/软删除过滤

数据完整性:
- 新增 8 个 FK 约束 (follow_up_task→appointment, points_transaction→account/rule/order,
  points_order→product/patient, offline_event_registration→event/patient)
- critical_alert/critical_alert_response version 字段 i64→i32 统一
- vital_signs_daily_service 聚合查询添加 DeletedAt.is_null() 过滤

代码规范:
- 新增 api/upload.ts 封装文件上传，ArticleEditor 改用 service 层
- 新增 messages.updateSubscription，NotificationPreferences 改用 service 层
- 修复 erp-message SSE 测试编译错误 (移除 serde_urlencoded 依赖)
