- Replace byte[] and Base64String with required Stream PdfStream - Simplify validators: remove XOR/Base64 validation, only check NotNull - Affected queries: ValidatePdfQuery, ValidatePdfAQuery, CheckPdfAttachmentsQuery, ExtractSwissQrCodeQuery - Memory efficiency: direct stream usage, no intermediate byte[] copies
