feat: 完成API测试、生产环境配置和文档编写

## 🧪 API测试系统完善 - 创建完整的单元测试套件 (tests/unit_test.go) - 认证流程、CRUD操作、文件上传测试 - 中间件、错误处理、性能测试 - 创建集成测试套件 (tests/integration_test.go) - 业务流程、数据一致性、并发测试 - 创建综合API测试 (test_api_comprehensive.http) - 92个测试场景，覆盖所有API端点 - 更新Makefile添加测试命令 - test-unit, test-integration, test-api, test-cover, test-bench ## 🗄️ 生产环境数据库配置 - Docker Compose生产环境配置 (configs/docker/docker-compose.prod.yml) - PostgreSQL 16 + Redis 7 + Nginx + 监控栈 - 数据库初始化脚本 (configs/docker/init-db.sql) - 完整表结构、索引优化、触发器、视图 - 生产环境配置脚本 (scripts/production-db-setup.sh) - 自动化配置、连接池、备份策略、监控 ## 📚 API文档完善 - 完整的API文档 (docs/API_DOCUMENTATION.md) - 详细接口说明、请求响应示例 - 认证流程、错误处理、性能优化 - SDK支持、部署指南、安全考虑 - 包含cURL示例和Postman Collection支持 ## 📊 项目进度 - 总进度: 50.0% → 57.5% - 中优先级任务: 55% → 70% - 并行完成3个重要任务，显著提升项目完成度 ## 🎯 技术成果 - 测试覆盖率大幅提升，支持自动化测试 - 生产环境就绪，支持Docker部署 - 完整的API文档，便于前后端协作 - 性能优化和监控配置，确保生产稳定性

+- 已配置合理的内存参数
+- 已优化 WAL 和检查点设置
+
+## 下一步操作
+1. 复制配置文件到 PostgreSQL 目录
+2. 重启 PostgreSQL 服务
+3. 启用自动备份 crontab
+4. 配置监控服务
+5. 运行性能调优脚本
+
+## 维护命令
+\`\`\`bash
+# 手动备份

+# 监控检查
