feat(valve): resolve supplier+type from asset registry, reject legacy asset fields

Mirrors the rotatingMachine cutover: assetResolver derives supplier/type/
units from the model id; nodeClass throws a clear "re-select model and
save" error if the saved node still carries denormalized supplier/
category/assetType strings. valve.html defaults trimmed accordingly.

14/14 tests pass.
