 * Shared Unreal asset path handling (#798).

 * Callers spell an asset path several defensible ways: with a `.uasset`
 * suffix, with the object suffix Unreal prints in the content browser, with
 * backslashes, or wrapped in the `{ refPath }` object reference that the
 * engine's own toolsets use. The bridge wants exactly one of those forms.
 * Repairing the rest at the boundary is cheaper than making every caller
 * discover the rule by trial and error, and a rejection that names the field
 * and shows the accepted shape is cheaper than a generic failure.
