Add 3 variables to API persistence/questionnaires/search/meta

[BulotF]

First used for the "home" page and the "search" page, this API is also used for the choice list on merging and composing questionnaires.

For the last need, 3 new variables are needed :

• Name : the business id, used for the questionnaire navigation
• flowLogic : needed to check if flows are the same : https://github.com/InseeFr/Pogues/issues/664
• formulasLanguage : needed to check if formula languages are the same : https://github.com/InseeFr/Pogues/issues/665
