admin 507b9c5704 feat: switch to MySQL, add Chinese comments, health check, and technical docs
1. 数据源切换至 MySQL:
   - app.py 从 SQLite 切换到 PyMySQL,所有 API 读取 MySQL weread_dashboard 数据库
   - 新增 db_required 装饰器统一管理数据库连接和异常处理
   - 新增 /api/health 健康检查接口,检测 MySQL 连接状态
   - MySQL 连接失败时返回 HTTP 503 和告警信息
   - 修复 fetched_at 字段 Unix 时间戳到 MySQL TIMESTAMP 的兼容问题

2. 前端数据库连接告警:
   - 页面加载时优先调用 /api/health 检查 MySQL 连接
   - 连接失败时显示固定告警横幅,阻止后续数据加载
   - CSS 告警横幅样式(黄色背景、下滑动画)

3. 代码中文注释:
   - app.py:所有函数、API 接口、工具函数添加完整中文文档注释
   - fetch_data.py:所有 SQLite 建表语句添加列级中文注释
   - migrate_to_mysql.py:保留已有中文注释

4. 技术文档与元数据文档:
   - docs/TECHNICAL_DOC.md:项目概述、系统架构、API 设计、部署指南
   - docs/METADATA_DOC.md:18 张表完整字段说明、索引、表关系、数据类型规范
