Python 3.13 is causing installation errors in CI/CD runners.
Upgrading to Python 3.14 which is the latest stable version.
Changes:
- pyproject.toml: Update python requirement to ^3.14
- pyproject.toml: Update MyPy python_version to 3.14
- pyproject.toml: Update Black target-version to py314
- .gitlab-ci.yml: Update PYTHON_VERSION to 3.14
- .github/workflows/build-deploy.yml: Update PYTHON_VERSION to 3.14
- .gitea/workflows/ci.yml: Update PYTHON_VERSION to 3.14
This fixes the CI/CD error:
"rm: cannot remove '/opt/hostedtoolcache/Python/3.13.9/x64/lib/python3.13/__pycache__': Directory not empty"
