Add comprehensive SEO support for property listing pages to improve organic search visibility and social sharing. Changes: - Convert listing detail page from client-only to server component wrapper with generateMetadata() for per-listing title, description, OG tags, canonical URLs, and hreflang alternates - Add JSON-LD structured data (Schema.org RealEstateListing) with price, location, property specs, and breadcrumb markup - Add Website JSON-LD with SearchAction to root layout - Upgrade sitemap.xml to dynamically include all active listings across both locales (vi, en) with ISR revalidation - Improve robots.txt with pagination/sort exclusions and GPTBot block - Create server-side fetch utility (listings-server.ts) for SSR data - Extract client UI into ListingDetailClient component Co-Authored-By: Paperclip <noreply@paperclip.ing>
