Bug: Several pyproject.toml files were not updated to require Python 3.14, creating an inconsistency with the Docker images which now use Python 3.14.
_{Severity: MEDIUM}

Suggested Fix

Update the requires-python setting in the root pyproject.toml, packages/ol-orchestrate-lib/pyproject.toml, and dg_projects/data_loading/pyproject.toml to require Python 3.14 (e.g., >=3.14,<3.15) to match the version used in the Docker containers.

Potential issue: The pull request updates the Docker images to use Python 3.14, but
several `pyproject.toml` files (in the root, `packages/ol-orchestrate-lib`, and
`dg_projects/data_loading`) were not updated to match. These files still allow for
Python `>3.13`, creating a discrepancy between local development and production
environments. This could lead to subtle bugs if code is developed against a different
Python version than what is run in the containerized production environment.
