Consolidate Organization schema, add ItemList/Offer markup, expand FAQ

- Merge the duplicate Organization/LocalBusiness JSON-LD blocks (home's
  LocalBusiness + o-kompanii's Organization) into one shared
  getOrganizationSchema() call rendered on every page. Deliberately NOT
  wired through the root layout: fetches there get frozen into the
  static shell at build time (backend unreachable during image build)
  and never revalidate, silently serving stale data to crawlers - each
  page calls it directly instead, where revalidation is proven to work.
- Add optional ItemList schema on /uslugi and Offer/OfferCatalog schema
  on /aktsii; entity pages (/uslugi/[slug] Service, /blog/[slug]
  Article) reference the organization via @id instead of duplicating it.
- Add 8 more real FAQ entries (pricing model, contract terms,
  onboarding time, hybrid IT staff setup, supported stacks, backups,
  152-FZ compliance, escalation) and give every FAQ its own slug and
  dedicated /faq/[slug] page with its own title/H1/FAQPage schema,
  modeled on the one-topic-per-page pattern (h/t remontka.pro).
