No services: /tjanster, booking steps, offers, galleries and downloads removed everywhere

Linus 2026-11-06: he offers no services; the site has posters and collaborations only. /tjanster went live with the
move to Cleura (it came with the SEO pull request #1) and was redirected to the start page in Caddy the same morning.

- tjanster.astro deleted; Tjänster out of the menu and the 404 page.
- Start page: "Vill du boka en fotografering?" -> "Vill du ha en bild på väggen?" (Se posters); "Så bokar du" ->
  "Posters och samarbeten"; description without "Boka via kundportalen".
- Portfolio intro points to the posters; privacy page: orders of posters and collaborations instead of bookings.
- JSON-LD: Organization instead of ProfessionalService, no ReserveAction, offer catalog, price range or service area.
- llms.txt: no prices, booking, booking steps, services page or booking FAQ; faq.ts keeps only the type.
