feat: Configure Docker and Devcontainer for development environment

This commit enhances the development environment by configuring Docker and the Devcontainer for improved development workflows.

- Updates the .devcontainer/Dockerfile to install Docker CE, configure the Docker socket, and clean up unnecessary files.
- Modifies the backend/Dockerfile to create a /logs directory and adjust permissions.
- Updates the .devcontainer/devcontainer.json to mount the Docker socket and set the PYTHONPATH.
- Updates the .devcontainer/docker-compose.yml to mount the logs directory and add an extra host for Docker.
- Adds imports to backend/core/tests/test_processes.py
