## PR-Codex overview
This PR updates the `EnsureValidConnectedWalletLoginClient` component to ensure that wallet addresses are compared in a case-insensitive manner by using the `checksumAddress` function.

### Detailed summary
- Added import of `checksumAddress` from `thirdweb/utils`.
- Updated the conditional check to compare `connectedAddress` and `props.loggedInAddress` using `checksumAddress` for both values.
