feat(health): 积分触发扩展 + 随访模板关联 — Phase 3

- 新增 follow_up.completed 事件积分消费者，随访完成触发 30 积分
- follow_up_task 新增 template_id FK 关联随访模板
- follow_up_record 新增 form_data JSONB 存储结构化表单数据
- 新增 POST /health/follow-up-tasks/from-template 基于模板创建随访任务端点
- 数据库迁移 160：follow_up_task.template_id + follow_up_record.form_data + 积分规则种子
