refactor: 4层架构重构 + 饮食VLM接入 + 多项修复

- 后端: remaining_endpoints拆分为6个独立文件 - 后端: AI Agent Handler从ai_chat_endpoints抽取为7个独立处理器 - 后端: 食物识别prompt改为输出结构化JSON - 前端: 饮食识别从Mock替换为真实VLM API调用 - 前端: 首页图片上传URL修复(/api/upload→/api/files/upload) - 前端: 拍饮食按钮导航到独立DietCapturePage - 前端: 删除无用agent_bar.dart - 前端: 修复widget_test.dart过期属性名 - 前端: 恢复ServicePackageCard和详情页 - 新增6份实施文档(情况/问诊/报告/建档/日历/视觉统一)
