StartBlobUpload

POST
/uplim.api.v1.InternalPipelineRunsService/StartBlobUpload

-------- Streamed (multipart) blob output (M0.5) -------- For PutBlobOutput / CommitBlobOutputFile on the side-car socket: the side-car streams bytes to S3 without any presigned URL or bucket credential crossing the socket to user code. The api holds the creds and initiates the S3 multipart upload; only the side-car sees the per-part presigned PUT URLs. StartBlobUpload → PresignUploadPart (per ~5MB part) → CompleteBlobUpload; the side-car then calls the existing FinaliseBlobOutput (same object key) for the metadata write.
