fix(health): 走查止血 — 患者名显示修复 + 枚举补全 + 医护统计 + 设备选择器

后端:
- alert_service: list_alerts 批量查询 patient_name 填充 AlertResponse
- consultation_service: list_sessions 批量查询 patient_name/doctor_name
- erp-ai handler: list_analysis 通过 raw SQL 查询 patient_name

前端:
- AlertList/AlertDashboard: 使用后端返回的 patient_name 替代 ID 截断
- ConsultationDetail: 使用 patient_name/doctor_name 替代 ID 截断
- AiAnalysisList: 使用 patient_name 替代 ID 截断
- constants/health: SEVERITY 补 high/medium, STATUS 补 active
- AdminDashboard: 医护人数改为 API 查询（useStatsData 新增 doctorCount）
- DeviceManage: 患者 ID 输入改为 PatientSelect 搜索选择器
