feat: enhance SEO and sitemap functionality

- Updated the sitemap generation to return a byte array instead of a string for improved performance.
- Added new SEO metadata for categories and store chooser routes to enhance search engine visibility.
- Implemented redirects for legacy wishlist URLs to the homepage, improving user experience.
- Updated robots.txt to disallow indexing of specific paths, ensuring better control over search engine crawling.
