feat: add URL routing for /me page tabs

- Add routes for /me/highlights, /me/reading-list, /me/archive
- Redirect /me to /me/highlights by default
- Update Bookmarks component to extract tab from URL path
- Pass activeTab prop to Me component based on current route
- Update Me component to use URL-based tab state instead of local state
- Update tab click handlers to navigate to appropriate URLs
- Enable deep-linking to specific tabs (e.g., /me/reading-list)
