fix(api): auto-run migrations on container start and fix ESM warning

- Add docker-entrypoint.sh that runs prisma migrate deploy before
  starting the app, ensuring all tables exist on deployment
- Add "type": "module" to package.json to eliminate Node.js ESM
  reparsing warning for eslint.config.js
