fix: auto-enable cluster bootstrap, add init-db.sql to postgres volumes

- Auto-enable cluster seeding when BOOTSTRAP_CLUSTERS is set
  (no longer requires separate BOOTSTRAP_ENABLE_CLUSTERS=true)
- Add BOOTSTRAP_ENABLE_CLUSTERS to README .env template
- Mount init-db.sql in postgres service volumes
