## PR-Codex overview
This PR focuses on refactoring the `SmartWalletsBillingAlert` component in the `Alerts.tsx` file. It updates the alert's UI and removes the dismissible functionality, while also changing the import paths for components used in the alert.

### Detailed summary
- Removed unused imports related to `Alert`, `AlertDescription`, `AlertIcon`, `AlertTitle`, `Flex`, and `IconButton`.
- Updated imports for `Alert`, `AlertDescription`, `AlertTitle`, `TrackedUnderlineLink`, and `CircleAlertIcon`.
- Removed the `dismissible` prop and related logic.
- Simplified the alert structure with a new layout.
- Changed the alert icon and styling.
