## PR-Codex overview
This PR updates the logic for determining if there are no assets in the
`WalletModal` component by including a check for `totalBalanceUsd`. This
enhances the condition to account for cases where the total balance is
zero.

### Detailed summary
- Modified the `noAssets` constant to check if either `topTokens.length`
is zero or `totalBalanceUsd` is zero, in addition to the existing
`!isLoading` condition.
