Develop fastapi (#6)

* feat: add side panel with navigation and storage cleaner functionality

* feat: add OpenUrlPage and integrate into app navigation

* feat: 添加 GlobalSnackbar 组件并在多个页面中集成，替换原有 Snackbar 实现

* feat: fix OpenUrl sidebar issue with architecture refactor

- 修复原问题：不再直接替换侧边栏 URL，保持插件导航可见
- 采用配置页 + 查看页分离架构：OpenUrlPage (配置) + OpenUrlViewerPage (查看)
- 支持多个 URL 快捷方式管理（添加/删除）
- 每个 URL 提供两种打开方式：在侧边栏打开 / 在新标签页打开
- 侧边栏查看页使用 iframe 占满全部剩余空间
- 更新 TypeScript 类型定义
- 保留原有混合内容警告检查
- 数据持久化到 Chrome Storage

* refactor: centralized route management - consolidate routing config into single source

* feat: 更换logo

* refactor: code review fixes - security and race condition improvements
