feat: 后端架构重构 — Endpoint→Service→Repository分层 + AI确认机制 + 异步任务持久化
- 核心业务拆分为 Endpoint → Application Service → Repository 三层 - AI写入操作必须用户确认后才写库(确认卡片机制) - 报告/饮食/用药分析改为持久化任务队列(原子领取/重试/重启恢复) - 运动计划修复: 连续真实日期替代周模板 - 用药提醒去重 + 通知Outbox预留 - 认证收拢到AuthService, 管理员收拢到AdminService - AI会话加用户归属校验防串号 - 提示词调整为患者视角 - 开发假数据已关闭 - 21/21测试通过, 0警告0错误
