feat(V40): EMPI患者主索引 — 完整前端+DB修复+5/6 API通过

前端:
- Patient页面: 注册/查询(全局ID/身份证)/统计卡片
- Merge页面: 合并操作+合并日志列表+撤销
- Statistics页面: EMPI统计概览

数据库修复:
- 创建empi_person表(global_id/patient_name/gender/birth_date/id_card_no等)
- 创建empi_id_mapping表
- 修复empi_patient_photo: 添加create_time列
- 修复empi_family_member/merge_log: 添加delete_flag/create_by/update_by列
- empi_person: 添加merge_status列

后端修复:
- EmpiPerson实体: name→patient_name列映射修复

测试: 5/6 API通过(注册/查询/照片/家庭/合并日志)
