Phase 1: technical SEO foundations

- Per-page titles, descriptions, canonicals, Open Graph/Twitter tags
  via a shared pageMetadata() helper; metadataBase on the root layout
- Sitemap generated from a route list on the canonical non-www host;
  robots.txt points to it; /services removed
- One H1 per page; decorative images get empty alt text
- JSON-LD: site-wide ComputerRepairService, FAQPage on the homepage,
  Service on each service page
- FAQ answers are now server-rendered (forceMount) so the schema matches
  the HTML; fixed the nested payment FAQ item
- Drop web design (page, nav link, homepage card and FAQs); 301 the old URL
- Remove GA, Facebook Pixel and Vercel Analytics/Speed Insights
- Fix tel: links (+640211... -> +64211...)
- Add og-image.png and logo.png
