✅ test(admin): 优化登录页面集成测试

- 添加@testing-library/jest-dom依赖以增强断言能力
- 统一使用TestWrapper包装组件，确保测试环境一致性
- 重构密码可见性切换测试，使用更可靠的元素查找方式
- 优化表单验证测试，移除过时的标签文本选择器
- 添加加载状态测试，验证表单提交时的按钮状态变化
- 改进样式类名测试，使用更可靠的非空断言
- 修复测试账号信息验证，使用更灵活的文本匹配器

♻️ refactor(test): 重构测试工具函数

- 添加AdminTestWrapper专门用于管理后台页面测试
- 实现localStorage模拟，避免测试间的状态污染
- 优化测试环境配置，确保AuthProvider正确集成
