feat(passport): 实现统一扫码功能并迁移二维码登录页面

将原有的扫码登录和扫码核销功能合并为统一扫码功能，支持智能识别二维码类型，
自动执行相应操作。同时将二维码登录相关页面迁移到 /passport 路径下，优化用户体验与代码结构。

主要变更：
- 新增统一扫码 Hook (useUnifiedQRScan) 和按钮组件 (UnifiedQRButton)- 新增统一扫码页面 /passport/unified-qr/index
- 迁移二维码登录页面路径：/pages/qr-login → /passport/qr-login
- 更新管理员面板及用户卡片中的扫码入口为统一扫码- 移除旧的 QRLoginDemo 和 qr-test 测试页面- 补充统一扫码使用指南文档```
