Summary:

The provided code changes are focused on updating the base Docker images used for the integration tests and the Django application deployment. These changes are primarily aimed at improving the security and reliability of the application by keeping the underlying dependencies up-to-date and implementing best practices for secure configuration and deployment.

The key security-relevant aspects of these changes include:

1. Python Version Updates: The Dockerfiles are being updated to use the latest versions of Python (3.13.1) to ensure the application is running on a secure and supported runtime.
2. Dependency Management: The code changes include updates to the requirements.txt files, which manage the Python dependencies. Regularly reviewing and updating dependencies is crucial to address potential security vulnerabilities in third-party libraries.
3. Secure Configuration: The Dockerfiles include steps to set appropriate file permissions, use non-root users, and configure TLS/SSL for secure communication. These are important security practices to harden the application's deployment.
4. Monitoring and Metrics: The Nginx-based Dockerfiles include options to enable metrics and monitoring, which can be useful for detecting and responding to security-related issues.

Overall, the changes appear to be focused on improving the security and reliability of the application's deployment, which is a positive step. However, it's important to thoroughly review the changes, test the application, and ensure that no new security vulnerabilities are introduced.
