fix(docker): ensure data persistence across container updates

- Update Dockerfile to set BUILDER to /build
- Update Dockerfile to set WORKDIR to /app
- Update docker-compose.yml to use a named volume for iphistory service
- Mount iphistory_data volume to /app directory in the container
- Ensure data is preserved when pulling the latest image and recreating the container
