feat(web): SEO — server-rendered template pages + /guides articles

- templates/[slug] converted from client to server component: per-template
  generateMetadata (title/description/canonical/OG) + SoftwareApplication
  JSON-LD; code-audit toggle split into a client island; missing/non-public
  templates now return a real 404.
- sitemap.ts pulls public template slugs live from the API (best-effort) +
  the new /guides routes.
- new /guides section: 3 server-rendered SEO articles (host MCP with OAuth,
  hosted-platforms comparison, MintMCP alternative) with TechArticle JSON-LD;
  Guides link added to the marketing nav.
- lib/seo.ts: articleJsonLd + templateJsonLd builders.
