ECL Record Layout metadata is not reported for CSV files in hthor

WsDFU/DFUInfo should report ECL record definition. The DFUInfo response seems purposely omit the ECL record definition for non-FLAT files.

Providing sample DFUInfo responce for accounts file created as FLAT, and as CSV via ECL output statement.

Note that the flat version contains ECL record definition, while the other one does not:
