chore(copy): drop AI-slop tells from marketing copy

Per encryption4all/dobby#44 — sweep marketing/SEO copy for AI-isms.

- Drop "enterprise-grade" superlative across en.json, nl.json,
  SEO.svelte default, and marketing JSON-LD.
- Replace trailing -ing participle ("ensuring full GDPR compliance
  and data sovereignty") with a plain statement.
- Replace rule-of-three brochure list ("Full transparency, no vendor
  lock-in, community-driven") with concrete language.

No functional or layout changes; only user-visible copy.

Closes #44
