seo: dynamic sitemap + robots + per-page metadata + JSON-LD

Brings the site up to enterprise SEO standards. Google now gets a complete machine-readable map of the content, with multilingual hreflang tags, structured data for the knowledge panel, and rich Open Graph cards on LinkedIn / WhatsApp / Twitter. NEW - src/app/sitemap.ts: dynamic sitemap.xml from Prisma. Emits 5 locales x every active application + every active news article, with hreflang alternates linking each translation. Hourly revalidation. - src/app/robots.ts: robots.txt blocks /hq-command/, /api/, /parts (B2B auth-gated), points crawlers at the sitemap. - src/lib/seo.ts: helpers for canonical URLs, hreflang alternates, and JSON-LD schemas (Organization, WebSite, Article, Product, BreadcrumbList). - src/components/seo/JsonLd.tsx: server component that emits one application/ld+json script tag per page. PER-PAGE generateMetadata - Home: localized titles + descriptions in EN/IT/VEC/ES/DE - News hub: title built from translations, hreflang tags - News article: title/description from DB, OG image = cover, type=article, publishedTime + modifiedTime for date freshness signals - Applications: title/description from DB, type=product, hero image - Heritage: localized title/description JSON-LD STRUCTURED DATA - Site-wide (in root layout): Organization (with HQ address, founder, contact, social profiles) + WebSite — drives Google knowledge panel - Article pages: Article schema with publisher/datePublished/dateModified — required for Google News / Discover eligibility - Application pages: Product schema (FLUX brand, RF Industrial category) + BreadcrumbList — drives rich-snippet breadcrumb in search results NOTES - Open Graph metadataBase set from NEXT_PUBLIC_APP_URL so absolute URLs for OG images are correct (LinkedIn previews require absolute paths) - All pages have canonical URLs to prevent duplicate-content penalties - /parts already has noindex meta (B2B portal) — also blocked in robots - No DB schema changes. Pure additions to /src/lib and /src/app.
