Implement multi-domain SEO improvements:

- Add metadata to login and login-verify pages to prevent indexing. - Update robots.txt to disallow additional sensitive paths. - Enhance sitemap generation to filter by city and include accurate last modified dates. - Refactor canonical URL generation to support multi-domain architecture, ensuring self-canonicalization for city domains. - Remove deprecated CanonicalHandler component and streamline canonical URL handling. - Introduce safe JSON-LD output to prevent XSS vulnerabilities. - Add payment layout with appropriate metadata to prevent indexing. - Conduct a comprehensive technical SEO audit and implement necessary fixes across the application.
