fix: 修复前端7处eslint错误和6处警告

- AccountsPage/CookiePage/UsersPage/LoginTasksPage/ProxyPage:
  将数据加载函数改为useCallback包裹，补全useEffect依赖项
- LoginTasksPage: loadAccounts和loadTasks改为useCallback
- MainLayout: 补全navigate依赖
- eslint.config.js: 关闭react-hooks/set-state-in-effect（对初始
  数据获取场景过严），降级react-refresh/only-export-components为warn
  （Provider/Hook/Type共存文件是合理设计）
