Get data pipeline details or Lambda node presigned URLs

GET 
/data-pipelines/:id

Default (no action) returns the stored pipeline plus AccessType and DataPipelineType (glue if omitted). Requires read-only access. Unknown action values are ignored and details are returned. action=upload-script or retrieve-script is AI Flow only and requires query node (LambdaFunction NodeName). Both return LambdaNodePresignedUrl with presignedUrl (PUT vs GET) and s3Location. Missing node, non-ai type, unknown node, or non-Lambda node is DP-1010 (HTTP 403). Code reads projection_expression (underscore, comma-separated). Spec projectionExpression is not applied on this handler.
