feat: 登录页5种主流高级风格重写 + 主题/登录页设置独立

5个登录组件全面重新设计:
- SplitView: 分屏聚焦风格(Linear/Notion) — 左55%深色渐变+几何动画装饰,右45%纯净表单+底线输入框
- CenteredCard: 沉浸渐变风格(Stripe/Vercel) — 紫蓝辐射背景+毛玻璃卡片+发光效果
- SidePanel: 品牌侧栏风格(Slack/Figma) — 左38%大号标语+feature pills,右62%宽留白表单
- FullImage: 粒子网格风格(GitHub/AWS) — CSS粒子光点+网格线+发光球体+深色内嵌卡片
- MinimalDark: 极简线条风格(Apple/Linear) — 纯黑背景+16px渐变圆点logo+宽字距+底线输入框

AppearanceSettings 主题与登录页完全独立:
- 界面配色区: 5种主题配色即时预览
- 登录页风格区: 5种风格缩略图预览+参考品牌标签(Linear/Notion, Stripe/Vercel等)
- 移除登录页主题切换按钮,风格与主题彻底解耦
