Update base image to an existing Python tag

readme_docs/Dockerfile now starts from python:3.14.2, but the official Python images currently only publish tags up to 3.13.x, so python:3.14.2 cannot be pulled. Any build of this image will fail immediately at the FROM instruction. Please pick a Python tag that actually exists (e.g., the latest 3.13.x or the previously used 3.9.x/3.10.x).

Untested Python version upgrade may break build

The upgrade from Python 3.9.15 to 3.14.2 is a significant version jump (5 major versions). The project's pyproject.toml classifiers explicitly list Python 3.9-3.13 as supported versions but do NOT include Python 3.14, indicating this version hasn't been tested. While the uv.lock has resolution markers for Python 3.14, the declared supported versions suggest potential compatibility issues. Features deprecated in 3.9 may have been removed in 3.14, which could cause the uv sync --locked command or the application itself to fail.
