feat: refactor conversations page into a workbench layout and implement workspace switching

- Migrate ConversationsPage to use ConversationWorkbench component.
- Create WorkbenchLayout to handle authentication and layout for workbench.
- Add WorkbenchPage to render ConversationWorkbench.
- Implement WorkspaceSwitcher for switching between dashboard and workbench.
- Update AuthProvider to manage authentication for both dashboard and workbench routes.
- Enhance WorkbenchHeader with user menu and workspace switcher.
- Add tests for workspace switcher and auth provider functionality.
- Update translations for workspace labels in English and Chinese.
- Exclude e2e tests from TypeScript compilation.
