Redesign deployment: only .env + docker-compose.yml needed on server

Custom Docker images embed all config so production servers no longer
need SQL files, kong.yml, or shell scripts. Kong generates config from
env vars at startup. Migrate container auto-detects fresh vs existing
DB and runs appropriate scripts.

New images: monacousa-db, monacousa-kong, monacousa-migrate
New commands: deploy.sh build-images, deploy.sh push-images
