Make reusable Python workflow dispatchable

Rename reusable workflow and add workflow_dispatch so the reusable workflow can be run manually with a Python version choice. Update PYTHON_VERSION env to read from either workflow_call inputs or workflow_dispatch event inputs. Remove duplicate workflow_dispatch inputs and the conditional in build-python.yml so the matrix always invokes the reusable workflow for each version (3.12.12, 3.13.12, 3.14.3). This simplifies manual runs and centralizes version handling in the reusable workflow.
