feat: 将项目从Next.js重构为Python Flask版本
完全重构为Python + Flask架构，包含： 1. 核心模块： - lib/db.py：数据库连接（PyMySQL） - lib/field_mapping.py：字段映射（100+字段英文→中文） - lib/report_generator.py：日报生成核心逻辑 2. Flask应用： - app.py：主应用，包含所有API路由 - 配置管理API（CRUD、启用/禁用、排序） - 日报生成API（支持预设/自定义时间） - 历史记录API（分页查询） - 文件下载API - 定时任务（APScheduler，每天8:01） 3. 前端页面： - templates/index.html：完整的单页面应用 - 三个标签页：配置管理、日报生成、历史记录 - 原生HTML+CSS+JavaScript，无需构建 4. 依赖管理： - requirements.txt：Python依赖清单 - Flask 3.0.0 + Flask-CORS 4.0.0 - PyMySQL 1.1.0（数据库驱动） - openpyxl 3.1.2（Excel处理） - APScheduler 3.10.4（定时任务） 5. 启动脚本： - scripts/dev.bat：Windows开发环境启动 - scripts/start.bat：Windows生产环境启动 6. 文档： - README.md：完整的安装、运行、使用指南 - 包含API接口说明、数据库表结构、常见问题 Windows运行方式： 1. 安装Python 3.8+ 2. pip install -r requirements.txt 3. scripts\dev.bat 或 python app.py 4. 访问 http://localhost:5000 5. 初始化数据库：POST /api/init-tables 所有功能完整保留： ✅ 定时任务（每天8:01） ✅ 配置管理（CRUD+启用/禁用+排序） ✅ 日报生成（按配置+时间范围） ✅ 历史记录（查看+下载） ✅ 自定义字段（中文显示） ✅ 求和功能（多字段求和） ✅ 按企业/用户拆分 ✅ Excel导出 Coze-Commit-Type: user Coze-User-ID: 3722323274763196 Coze-Conversation-ID: 9894087
