add RETURN_SCENARIO env variables

Datamodel scenario feedback in any environment

A feature to help debug AnyLogic model results. This setting is used in the /wt/api/nextjs/v2/holon/ endpoint to determine whether to send back the used scenario (through the serializer) or not. This should ideally not be set to true in production since it will impact performance.

RETURN_SCENARIO=True

One thing I'm unsure of is whether setting the Azure settings to this setting will be able to toggle this functionality without having to push a new container. If yes, then we can use this setting to develop with the content on main and later disable the functionality when we are happy with the outcomes.

Doel je hier op de grootte van de response of triggert de serializer database queries? Want de response is ~175kb uncompressed dus dit valt wel mee.

Idee: dit met een cookie te zetten ipv enviroment variable. Dan kan een modelleur die cookie setten als hij het wilt zien.
