feat(SEO): implement SEO configuration and meta tag management

- Added SEO defaults and route-specific configurations for improved search engine visibility. - Introduced functions to normalize paths and retrieve SEO settings based on the current route. - Enhanced server-side rendering to dynamically update meta tags for title, description, and robots directives. - Created a utility for managing SEO-related meta and link tags in the frontend, ensuring consistent application of SEO practices across routes. - Updated sitemap with new last modification dates and removed outdated entries for better search engine indexing.
