fix: use npm install instead of npm ci, change port to 3091

- npm ci requires a package-lock.json; use npm install --omit=dev instead
- Change all port references from 3001 to 3091 (3001 is occupied)
  - docker-compose.yml: ports, PORT env, healthcheck URL
  - Dockerfile: EXPOSE
  - .env.example: PORT default
