Display an error message when the enrichment is empty

[BalamSal]

There is no error message when the user try to do and enrichment and it comes out as empty columns.

There should be a message to inform the colums are empty. There should be a message to check all the steps to do an enrichment such as the concept association in the description section, check if the service used is the right one, check if the minimum data is given to do the enrichment (exemple : for the geocodage the service need at least the number, the street and the city) etc ...

In the enrichment section, the "error" and "status" fields should be more descriptive and grouped in an other category at the begining or at the end of the list .
When the user selects "error" or "status", it display [object Object] on the bar of the selected fields of the enrichment.
