feat(web): Q3 前端体验优化 — ErrorBoundary + 5 hooks + 共享类型 + i18n 基础

- ErrorBoundary 组件：全局错误捕获与优雅降级
- 提取 5 个自定义 hooks：useCountUp, useDarkMode, useDebouncedValue, usePaginatedData, useApiRequest
- 从 11 个 API 文件提取 PaginatedResponse 共享类型到 api/types.ts
- 统一 API 错误处理（api/errors.ts）
- client.ts 迁移到 axios adapter 模式（替代废弃的 CancelToken）
- 添加 react-i18next 国际化基础设施 + zh-CN 语言包
