feat(profile): enhance ChargeCreditWallet with return URL handling and continue shopping button

- Added support for return URL handling in ChargeCreditWallet to improve user experience after payment.
- Introduced a "Continue Shopping" button that allows users to navigate back to their previous shopping session after successfully charging their wallet.
- Updated the component to manage pending return URLs and ensure they are saved and retrieved correctly.

These changes enhance the functionality of the ChargeCreditWallet page, providing a smoother transition for users post-transaction.
