fix(health): 修复审计发现的 10 个 CRITICAL 问题

权限与安全:
- 为全部 51 个 handler 端点添加 require_permission 权限检查
- 修复 CAS 预约操作中 doctor_id 为 None 时使用 Uuid::nil() 的问题

状态机修复:
- 预约初始状态从 "scheduled" 改为 "pending"（匹配设计规格）
- 排班状态从 "active" 改为 "enabled"
- 咨询会话添加 waiting→active 自动触发（首条消息时）
- 新增 create_session 端点和 DTO

数据完整性:
- doctor_profile 表添加 name 列（entity + migration + service）
- lab_report/health_trend 的 json 列改为 json_binary（支持 GIN 索引）
- 添加关键索引：patient.id_number UNIQUE、patient_tag UNIQUE、
  doctor_schedule 唯一排班槽位、health_trend、doctor_profile.name
- 随访记录完成后自动检查 next_follow_up_date 创建后续任务

事件总线:
- 实现 10 种核心事件发布（patient/appointment/follow_up/consultation/lab_report）
- 实现 workflow.task.completed 和 message.sent 事件订阅框架

种子数据:
- 实现 seed_tenant_health（8 个默认患者标签）
- 实现 soft_delete_tenant_data（16 张表级联软删除）
