feat(health): Phase 1 业务改进 — 诊断编码/统计API/体征表合并/积分修复

1.1 Dashboard 统计: 新增 3 个统计端点 (patient/consultation/follow-up)
1.2 事件发布: follow_up.overdue + health_data.critical_alert 事件
1.3 体征表合并: vital_signs 添加 source 列, daily_monitoring 委托写入
1.4 实时预警: 创建体征时检测血压/心率/血糖异常并发布事件
1.5 诊断编码: 新建 diagnosis entity/service/handler + ICD-10 支持
1.6 积分过期: expire_points 定时任务 + 修复 r#type 列名问题

修复: points_transaction.r#type → transaction_type 列重命名
修复: consultation_message.sender_type → sender_role SQL 列名
前端: 3 个统计 API 从伪实现改为真实调用
