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

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Changes:

- wxt.config.ts: Remove unused `debugger` permission (no code uses it)
- OpenUrlPage.tsx: Fix unreachable showMessage after window.close()
- OpenUrlPage.tsx: Replace unnecessary div wrapper with Fragment to reduce DOM nesting
- OpenUrlViewerPage.tsx: Add URL validation to prevent XSS via javascript:/data: URLs
- OpenUrlViewerPage.tsx: Add sandbox attribute to iframe for security isolation
- OpenUrlViewerPage.tsx: Add error handling for invalid URLs
- StorageCleanerPage.tsx: Fix race condition in handleOptionChange preference saving
- StorageCleanerPage.tsx: Remove unnecessary storage reads when saving preferences (use state directly)
- StorageCleanerPage.tsx: Add timeout cleanup for setTimeout to follow React best practices

* feat: implement drill-down navigation with master-detail dashboard

* feat: enhance dashboard dynamism and refine options UI

* feat: overhaul storage cleaner UI with real-time size estimation and modern aesthetics

* feat: overhaul TimestampPage UI/UX and fix GlobalSnackbar positioning

* fix: decouple popup routing from storage sync and enhance OpenUrlPage UI

* fix: avoid closing sidepanel when opening URL preview from within sidepanel
