Pull request overview

This PR attempts to upgrade the Python base Docker image from 3.8-slim to 3.14.2-slim to address 5 security vulnerabilities (1 critical, 4 high severity) in Debian 12 packages. However, the specified Python version does not exist, making this PR non-functional.

Key Changes:

• Updates the base Docker image from python:3.8-slim to python:3.14.2-slim

Critical Issue:
The PR specifies Python 3.14.2, which has not been released. As of January 2025, Python 3.14 does not exist. A valid stable version like 3.13.x or 3.12.x should be used instead to achieve the security goals.
