[4h] Add Dockerfile and Docker Compose configuration (Совершенствование ci/cd, чтобы билд собирался автоматом по нажатию "одной" кнопки)

この issue には説明がありません。

The issue title mentions adding Dockerfile and Docker Compose for automated builds, but the description is empty. First, examine the existing project structure to understand the Python/Django application setup. Look for existing CI/CD configuration files and dependencies. Determine the base image, required environment variables, and service dependencies for a multi-container setup. The goal is a configuration that allows a one-command build and run.
