feat(seo): facts in src/data/business.ts, SEO + JSON-LD components in layout

- business.ts: single source of truth; unknown facts (city, area, prices,
  packages, phone, delivery time, experience, testimonials) are null and are
  skipped everywhere. faq.ts builds answers only from known facts.
- portfolio-meta.ts: data hook for real per-image alt texts.
- SEO.astro: title, description, canonical, Open Graph, Twitter, og:image
  (EXIF-free JPG via getImage, absolute URL).
- SchemaOrg.astro: @graph with WebSite, Person, ProfessionalService
  (sameAs, ReserveAction to the customer portal, offer catalog without
  prices), WebPage, optional FAQPage and BreadcrumbList.
- MainLayout: lang=sv, Swedish nav (adds Tjänster), consent banner and
  footer in Swedish, lyxlimo/karleksguiden line removed, info@ address.
