Integrate Ledger app into "Import wallet" sign-up flow #832
Description
It would unlock Wander usage from a cohort of customers who store $AR/$AO on a Ledger hw wallet.
There is a Ledger app for the Ledger S that is used by Arweave users who hold a lot of $AR token (and $AO token). But today, there is no wallet UI that integrates with Ledger and can be used for $AO transactions. These new customers would come to Wander and use $AO apps more if this integration was built.
