📝 Description

This fix (#7230) introduced a performance regression in some cases (e.g. when a lot of tokens are defined in the currencies field of the manifest) as we now get the currency list again and again.
This PR only removes the listing of currencies that we were doing on all apps even if it was not using the dapp browser v3, this helps most apps for the moment but we still need to improve the performance of the currency listing.

In a next PR we'll try to remove the spreading done on tokens, only do the minimal work necessary to get the informations and try to improve caching on this by instead listening to changes to only pull currencies when it updates.
