fix(papermark): add missing EE env vars, increase RAM to 4096, add NODE_OPTIONS for build

- HANKO_API_KEY and NEXT_PUBLIC_HANKO_TENANT_ID are required at build time
  (module throws hard error if unset during page data collection)
- QSTASH_TOKEN, NEXT_PRIVATE_DOCUMENT_PASSWORD_KEY, NEXT_PRIVATE_VERIFICATION_SECRET
  added as placeholders/random values
- NODE_OPTIONS=--max-old-space-size=3584 for npm run build (Next.js OOM fix)
- RAM raised from 2048 to 4096 (Next.js build requires ~3.5GB heap)
