- Split all page.tsx files into server wrapper (metadata export) + client.tsx (Apollo/interactive)
- Add robots.ts and sitemap.ts (tournaments, teams, players)
- Add metadataBase, OpenGraph and Twitter card metadata to root layout
- Replace hardcoded worldcup.pivoine.art with NEXT_PUBLIC_SITE_URL env var (sitemap/robots) and relative paths (page metadata, resolved by Next.js against metadataBase)
