PdfProcessing: A CryptographicException because MD5 not available on Blazor WASM
Grid PDF Export fails on Blazor WASM with CryptographicException: MD5.
Root Cause: PdfExportContext.CreateDocumentId() calls System.Security.Cryptography.MD5.Create(). MD5 is not available in the .NET WASM runtime by default and throws CryptographicException.
