Hugh A Miles II	dbea4b6c87	feat(export): S3 upload + presigned URL utility ... Add superset.utils.s3 with upload_file_to_s3() (boto3 managed multipart) and generate_presigned_url(). Credentials/region come from the standard boto3 chain; operators can override client construction via EXCEL_EXPORT_S3_CLIENT_KWARGS (e.g. endpoint_url for MinIO/LocalStack). Adds unit tests with mocked boto3. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-16 14:48:34 -07:00
