Add wallet disconnect button

[mkermani144]

Description

The "connect" button in the ChooseWalletModal.tsx component should become "disconnect" when a wallet is connected. The disconnection logic should also be implemented in useWallet hook.

This looks to have already been completed.

Dear @twobitEDD We have already implemented the disconnect button on the bridge form, which is unrelated to this issue. We will resolve this matter as soon as possible
