feat: 添加社交登录和注册链接

核心改动:
- 将社交登录/注册按钮改为实际可跳转的外部链接
- 新增 SOCIAL_LINKS 配置对象
  * GitHub 链接指向项目仓库
  * Google 链接指向文档站点 (https://halolight-docs.h7ml.cn)
  * WeChat 链接指向组织主页 (https://github.com/halolight)
- 添加安全属性: target="_blank" + rel="noopener noreferrer"
- 改进代码可维护性：移除占位函数，使用配置化管理

修改文件:
- 登录页面: login.tsx/vue/astro 等
- 注册页面: register.tsx/vue/astro 等
