Looks like python is no longer being updated by Dependabot, so this is no longer needed.

Dependabot closed this itself when #235 merged, which is the config working as intended: the docker group is now patch only, and python:3.11-slim has no reachable patch bump.

For the record, the bump itself was technically sound. Running the API test suite inside a python:3.14-slim image gives 205 passed, identical to the 3.11 control; the app boots with all 105 OpenAPI paths; and every compiled dependency has a cp314 linux wheel (psycopg2-binary, sqlalchemy, pydantic-core 2.46.4, with bcrypt on abi3). The OS layer does not move either, since python:3.11-slim and python:3.14-slim are both Debian 13 trixie today with the same ffmpeg 7.1.5 and ImageMagick 7.1.1.

What was missing is CI coverage, not correctness. Backend Tests installs Python 3.12 on the runner and Docker Build only proves that pip install resolves, so nothing in CI executes the interpreter the container actually ships. A move to 3.14 should carry ci.yml's python-version in the same PR. One thing to bring along: pytest-asyncio 0.26.0 calls asyncio.get_event_loop_policy(), deprecated on 3.14 and removed in 3.16.
