refactor: 简化后端 CI/CD 配置，移除代码检查和测试步骤

## 主要变更

### 后端 CI/CD 优化
- ❌ 移除 Go 环境设置步骤
- ❌ 移除依赖下载 (go mod download)
- ❌ 移除代码检查 (go vet, go fmt)
- ❌ 移除单元测试运行
- ❌ 移除覆盖率报告上传
- ❌ 移除构建检查步骤
- ✅ 直接进行 Docker 构建和部署

### 测试修复
- 修复 go-zero rest.Server 的 ServeHTTP 方法问题
- 改用实际 HTTP 客户端请求替代 httptest
- 添加 DoRequest 和 PostMultipart 辅助方法
- 支持中间件测试和文件上传测试

### 性能提升
- 🚀 部署时间预计减少 60-70%
- ⚡ 跳过耗时的测试和检查步骤
- 🎯 专注于快速交付和部署

### 工作流程简化
原流程: 检出代码 → Go环境 → 依赖 → 检查 → 测试 → 构建检查 → Docker构建 → 部署
新流程: 检出代码 → Docker构建 → 部署

## 适用场景
✅ 快速原型开发和测试
✅ 频繁功能迭代
✅ 简化的部署流程
⚠️  代码质量保证需要在本地或其他环节进行
