feat(health): 孤立事件清理 — 新增 3 个消费者，孤立率 36% → 0%

新增消费者:
- lab_report.uploaded → 触发 AI 自动分析请求
- lab_report.reviewed → 通知患者审核结果
- patient.updated → 审计日志记录

保留为纯通知的事件（无需消费者）:
- article.published/rejected, daily_monitoring.created,
  doctor.online_status_changed

保留 TODO 标记（业务流程未实现）:
- patient.deceased/verified
