Reduce Vercel execution costs and Upstash Redis read counts by letting the CDN absorb more traffic. Addresses the "double dip" where bootstrap.js hit Redis for 15 keys on every 60s cache miss, and telegram-feed/geo had no s-maxage at all (every request hit Vercel). - bootstrap: s-maxage 60→600, add stale-if-error=900 - ais-snapshot: s-maxage 180→300, stale-while-revalidate 300→600 - oref-alerts: s-maxage 5→180, add stale-if-error=600 - telegram-feed: add s-maxage=600, stale-if-error=900 (had none) - geo: add s-maxage=3600, stale-if-error=3600 (had none) - gpsjam: add stale-if-error=3600 - opensky: add stale-if-error=300 - version: add stale-if-error=3600 - download: add stale-if-error=600
