- Remove outdated static public/sitemap.xml that conflicted with dynamic sitemap.ts
(was missing leistungen pages, city pages, and had outdated blog/portfolio slugs)
- Fix robots.ts to reference only the single sitemap.xml instead of non-existent
language-specific sitemaps (sitemap-de.xml, sitemap-en.xml, sitemap-sr.xml)
- Dynamic sitemap.ts now handles all pages with proper hreflang alternates
