KNOWN_INVALID_TYPES (FormDataStructure, FormDataCollection, FormDataTree,
etc.) was checked but only produced a Write-Warning/print warning — the
script still emitted the bad <v8:Type> into Form.xml, which XDTO later
rejected with a cryptic load-time error. Turn the warning into a hard
throw so misuse is caught at compile time with the correct hint.
Reveals two broken test cases that shipped invalid forms:
- form-compile/catalog-form: main attribute was FormDataStructure, fixed
to CatalogObject.Товары (what ERP's reference catalog forms actually
use with the cfg: prefix).
- form-info/overview: preRun form-compile used the same wrong type, fixed
the same way; snapshot regenerated.
Bumps form-compile to v1.4 on both runtimes.
