feat(rotatingMachine): resolve supplier+type from asset registry, drop denormalized fields

specificClass._setupCurves now calls assetResolver.resolveAssetMetadata
to derive supplier/type/units from the model id, instead of trusting
denormalized fields on the node config. If the model isn't in the
registry, installs a null-predictor stub and logs a clear "pick a model
from the asset menu" error rather than crashing.

rotatingMachine.html: defaults block trimmed (supplier/category/assetType
were stale copies of registry data).

Tests:
- New test/basic/assetMetadata.basic.test.js covers the registry-resolve
  path and the missing-model fallback.
- nodeClass-config / error-paths / nodeClass-routing / factories /
  abort-deadlock fixtures updated to the trimmed asset shape.
- 209/209 tests pass.
