将框架从 Flask 迁移到 FastAPI
主要改动： - 更新依赖：使用 fastapi、uvicorn 替代 Flask - 数据库层：从 Flask-SQLAlchemy 迁移到纯 SQLAlchemy - 新增 database.py 管理数据库连接和会话 - 路由层：从 Blueprint 迁移到 APIRouter，添加 Pydantic 模型验证 - 应用层：使用 FastAPI 中间件替代 Flask 插件 - 启动方式：使用 uvicorn 替代 Flask 开发服务器 - 更新 Docker 配置以支持 FastAPI 优势： - 更高的性能和异步支持 - 自动生成 OpenAPI 文档 - 更好的类型安全和数据验证 - 所有 API 端点保持向后兼容 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
