Merge pull request #12 from router-for-me/main

sync: merge upstream router-for-me/Cli-Proxy-API-Management-Center

主要更新：
- 登录页面重新设计（分屏布局 + 自动登录 UI）
- AI 提供商编辑改为独立页面（替代弹窗模式）
- 新增浮动导航侧边栏，支持快速跳转
- OAuth 模型别名和排除模型编辑页面
- 新增多个模型图标（Codex、DeepSeek、GLM、Grok、Kimi、MiniMax）
- 页面过渡动画优化，防止空白闪烁
- 日志页面新增原始日志显示开关
- 移动端响应式布局优化
- 配额管理新增认证类型统计

冲突解决：
- src/stores/index.ts: 保留本地 useDisabledModelsStore 和 PR 的 useOpenAIEditDraftStore
- src/pages/AiProvidersPage.tsx: 采用 PR 版本（页面导航重构）
