feat(tabs): implement default route titles for new tabs and navigation updates

- Introduced `getDefaultRouteTitle` utility to provide translated titles for various routes.
- Updated tab creation and navigation logic in `AppShell`, `Sidebar`, and `useTabs` to utilize the new title mapping.
- Enhanced internationalization support by adding new keys for default tab titles in multiple language files.

These changes improve the user experience by ensuring that tabs display meaningful titles based on their content, enhancing navigation clarity.
