Switch to Python 3.12 and regenerate poetry.lock to unblock Pillow up…

[rpancham]

This PR updates the container runtime to use Python 3.12 and aligns project metadata and dependencies accordingly.

Changes included:

• Establish Python 3.12 in the Dockerfile so all dependency resolution occurs under Python 3.12.
• Update the Python version constraint in pyproject.toml to allow Python 3.12.
• Regenerate poetry.lock under Python 3.12 to ensure consistent and reproducible dependency resolution.

This unblocks upgrading Pillow to a supported version (>=12.1.1), addressing the identified security vulnerability. No functional behavior changes are expected beyond the runtime and dependency alignment.
