Fix navigation accessibility for token generation and admin pages

- Add API Tokens navigation link to all user templates (dashboard, analyze, train, history, settings)
- Add Admin navigation link for admin users across all templates
- Remove old API token generation button from settings page (now uses dedicated page)
- Ensure consistent navigation experience across the application
- Admin users can now easily access user management and token generation pages
