test(handler,middleware,server): 新增 try_files、错误页面、pprof 单元测试

- static_test.go: 新增 try_files 配置解析、占位符解析、SPA 场景测试
- errorpage_test.go: 新增错误页面管理器完整测试覆盖
- errorintercept_test.go: 新增错误拦截中间件功能测试
- pprof_test.go: 新增 pprof 性能分析端点测试

// Package handler 提供错误页面管理器功能的测试。
//
// 该文件测试错误页面管理模块的各项功能,包括:
// - 管理器构造函数
// - 空配置处理
// - 部分加载失败处理
// - 全部加载失败处理
// - 错误页面查找
// - 默认页面 fallback
// - 状态码检查
// - 响应码覆盖
// - 配置状态检查
