feat(consent): benefit-led banner copy + analytics-only consent

- Warmer, accurate trilingual cookie-banner text to lift voluntary
  opt-in (EN/MK/SI), keeping Accept and Decline equally one-click
  (GDPR-compliant, no dark patterns).
- grant() now grants analytics_storage only; advertising consent stays
  denied, matching what the banner discloses (MSOS runs no ads).
- Cache-bust bump so the updated consent.js is fetched.
  (Cookie-withdrawal link already present in footer via msosOpenConsent.)
