feat: 引入 EF Core Migrations + 后台任务/校验修复 + 前端四态

后端
- 改用 EF Core Migrations(InitialCreate),Program.cs 用 MigrateAsync + AUTO_MIGRATE 开关 + 显式 MigrationsAssembly;移除 EnsureCreated、删除手写 DatabaseSchemaMigrator
- 修复后台任务永久卡 Processing:三个队列对超时且达上限的任务原子标记 Failed
- 修复报告重试失效:基础设施异常向上抛激活 RetryAsync,停机取消不计失败
- 修复 AI 用药天数 off-by-one(结束日为包含式)
- AI 报告日志不再记录 VLM 健康正文
- 新增统一输入校验(ValidationException + 中间件映射 400):血压/心率/血糖/血氧/体重范围、药名/日期/服药时间去重、饮食热量与评分、运动时长上限
- 删除健康数据 AI 录入的影子直写路径,统一走 Service 校验

前端
- 新增 AppErrorState / AppFutureView,用药列表、服药打卡、运动计划、随访列表改为 加载/失败/空/数据 四态,失败可重试

瘦身
- 删除过时的 DataSeeder / DevDataSeeder 及调用
- 删除依赖实时服务的 ai_agent_tests 集成测试
