fix: 修复前端构建问题 - 恢复 develop 分支配置

- develop 分支已包含完整的 package.json、tsconfig.json、vite.config.ts
- develop 分支已包含完整的路由、useAuth、api/tasks 实现
- @/ 路径别名已在 tsconfig 和 vite 配置中正确设置

额外修复：
- 删除 Next.js 残留文件 (next.config.js, next-env.d.ts)
- 删除死代码：workspaceStore.ts（从未被引用）、QuotaDisplay.tsx（从未被使用）
- 删除 Vite 脚手架残留：App.tsx、App.css
- Header.tsx 添加 Header.css 导入，修复顶部导航无样式问题
