feat(analytics): activate GA4 (G-KQ1JRV3KN7) + GDPR privacy page + GSC support

Client provided the GA4 Measurement ID and approved the standard policy.

- Activate analytics: NEXT_PUBLIC_GA_ID set to the FLUX property
  G-KQ1JRV3KN7 in the env template, with the same value as the
  docker-compose build-arg fallback so it works out of the box on deploy.
  (GA Measurement IDs are public — they ship in page HTML — safe to commit.)
- New GDPR-compliant Privacy & Cookie Policy page at /[locale]/privacy
  (all 5 locales), linked from the consent banner. Includes a clearly
  marked template disclaimer for legal review and a TODO on the contact
  email. Added to sitemap.
- Consent banner now links via the locale-aware next-intl Link.
- Google Search Console: optional NEXT_PUBLIC_GSC_VERIFICATION env var
  emits the google-site-verification meta tag (Dockerfile arg +
  docker-compose wired). Empty by default.

Verified: build inlines G-KQ1JRV3KN7 into the client bundle; the 5
/privacy routes render; TypeScript clean.
