// Multipart upload — ObjectTypeId hardcoded to OBJECTDXPASN server-side (never client-supplied),
// same pattern as UploadKycDocument.cs. ObjectId is typically 0 (the ASN's TMMHEAD row doesn't
// exist yet) — RowGuid is what AsnBLL.CreateAsnAsync later resolves via UAS's two-phase pattern.
// Uses the TENANT database (not DXPDb) since that's where the ASN's TMMHEAD row will live.
