Fix ESM component module resolution

[philippjfr]

Previously we used the Model.name to determine the name of the JS module inside a bundle. However the name seemingly is sometimes overwritten making this approach brittle. Instead we now use the class_name property, which was previously kebab case but is now passed through directly and only transformed into kebab case client-side.
