chore(deps): bump python from 3.12-slim to 3.14-slim

[dependabot]

Bumps python from 3.12-slim to 3.14-slim.

Superseded by our aligned Python 3.14 bump (Dockerfile multi-stage builder+runtime, CI python-version: 3.14, mypy 3.14). Closing in favor of that change rather than merging this Dependabot PR (it conflicted with the multi-stage Dockerfile).

Closing as superseded by the coordinated Python 3.14 upgrade.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
