Adapt user_data.adress extraction

[OphelieMicoine]

define userAddressData from user_data.address[0] if exist, from user_data.address otherwise.

@desaip @wyattr @SurendraJambeLI Hello ! can you consider my pull request please ?

Good catch — this is a real bug. The GTM data layer can pass user_data.address as either an array or a plain object depending on the tag configuration, and the current code only handles one format.

I ran into the same issue and took a similar approach in #17. One difference: my PR also adds a fallback for other address subfields (city, region, postal_code, country) using the same array-vs-object check pattern, since those can have the same inconsistency.

Might be worth coordinating to get one merged cleanly — happy to close mine in favor of this one if you expand the fix to cover the other subfields.

Thanks for your answer. I will cover the other fields and come back to you as soon as it is done.
