Add revocable ad consent settings and centralize ad slot configuration

[Copilot]

This updates the ads/settings flow so consent can be revoked after initial choice, and removes scattered empty AdSense slot placeholders in favor of a cleaner admin-ready configuration path. It also tightens the remaining approval-risk article content by reducing a long reproduced block to a brief quoted excerpt with personal framing.

• Consent controls

  • Adds a compact Ads settings control to privacy.html with a revoke-consent action.
  • Persists the revoked state in the existing consent key used by the ad loader.
  • Exposes revokeConsent() and consent-state accessors from site-ads.js for shared front-end behavior.

• Ad slot configuration

  • Replaces inline empty data-ad-slot="" placeholders with semantic data-ad-slot-key markers across home, search, and article placements.
  • Centralizes slot resolution in public/site-ads.js via an AD_SLOT_CONFIG map with optional window.SSF_AD_SLOTS override support.
  • Keeps unconfigured placements hidden until a real slot value is provided, which is cleaner for admin setup and safer for ad-policy handling.

• Article tightening

  • Refactors the long reproduced manifesto block in what-vibe-coding-means-to-me-2026.html into a short quoted excerpt.
  • Keeps the passage anchored as part of the author’s life anecdote while reducing approval and copyright risk.
