feat: Handle offline mode in Flagship app

[Ldoppea]

We want mespapiers to be compatible with the new Flagship app's Offline mode

When hosted in a Flagship app's WebView we now want to use FlagshipLink instead of StackLink in cozy-client

This link will allow to redirect all queries to the Flagship app that will handle data access when offline but also when online
