The 243-line legacy AssetMenu was retained for backwards compatibility
but no code in the refactored platform references it. Removed.
loadCurve removal stays deferred — rotatingMachine + valve still call
it through src/curves/curveLoader.js and src/curve/supplierCurve.js.
Migration to loadModel is a follow-up after the platform refactor lands
on main.
113/113 basic tests pass.
