Multi-wallet list view with cumulative balance #593
Description
Summary
Add a dedicated page that lists all wallets with their individual balances and a cumulative total balance across all wallets.
Details
- Show a list view of all wallets with each wallet's balance
- Display the cumulative balance across all wallets
- Consider also adding wallet totals to the sidebar for quick visibility
Why
As users accumulate multiple wallets, there's no way to see an overview of all balances at a glance or know your total holdings across wallets.
