Native l10n_es_edi_tbai hardcodes ClaveRegimenIvaOpTrascendencia '19' for
REAGYP vendor bills, but '19' only exists in the issued-invoices book. The
Batuz LROE schema for received invoices rejects it (cvc-enumeration-valid),
where the valid REAGYP-compensation key is '02'.
Override _l10n_es_tbai_get_vendor_bill_values_batuz to remap 19 -> 02.
