fix(wallet-mobile): NetworkError instance

This one was confusing. Not sure why we have NetworkError exported from @yoroi/common, but it's not the same one the wallet is throwing, so don't mix them up because then instanceof will fail.

maybe it's worth to still use the common package error but catching it by instance and use the UI error messages?

Well, sure, we can use the one in common everywhere instead. None of the uses I see use the message from the error itself.

The network error inside wallet is legacy, there are 2 fetchers, the legacy fetch, and the fetchData, which is the new one. There will be few places to replace. Please update them all to use -> from types Api.Error.Network, from types, the errors inside common can be dropped.
