Fixes #200.
Fuel nodes deliberately have blank labels in the rendered energy-system diagram, but exporting those blanks to GraphML leaves editors such as yEd without a readable fuel name.
Populate missing fuel labels with the node identifier in a copy used for GraphML export. Keep custom labels, the original graph, and the graph passed to the diagram renderer unchanged.
The regression round-trips the actual GraphML file and checks labels and edges, plus unchanged diagram labels. Only the external Graphviz image-rendering call is mocked.
Validation on Python 3.13: the missing-label regression fails before the fix; the full test suite passes afterward (254 passed, 1 existing skip). Black passes. Flake8 passes with the repository's setup.cfg (
python -m flake8 --config setup.cfg src/otoole/visualise/res.py tests/test_visualise.py, exit 0).git diff --checkpasses.Prepared with Codex assistance.
