## PR-Codex overview

This PR focuses on modifying the `BuyWidget` component to allow users to bypass wallet connection if a `receiverAddress` is provided. It updates the logic for displaying connection prompts based on the presence of this address.

### Detailed summary

- Updated `BuyWidget` to not require wallet connection if `receiverAddress` is set.
- Removed `activeWalletInfo` dependency from the condition for displaying the `FundWallet`.
- Introduced `showConnectButton` variable to determine if the connect button should be shown.
- Simplified the rendering logic for the connect button in `FundWallet`.
