chore: modernize Docker setup with Python 3.13 and env_file integration

- Upgraded base image to python:3.13-slim.
- Optimized Docker layer caching (requirements first).
- Integrated env_file: .env in docker-compose.yml for consistency.
- Added build-essential to support potential C-extension libraries.
