Refactor Docker setup for API and Streamlit services

- Updated docker-compose.yml to use new Dockerfiles for API and Streamlit services.
- Created Dockerfile.apipredict for the API service with necessary dependencies and configurations.
- Created Dockerfile.streamlit for the Streamlit service, including installation of requirements.
- Adjusted volume paths in docker-compose.yml.
