[SDK] Test: Replace deprecated checkContractWalletSignature use (#4949)

<!-- start pr-codex -->

## PR-Codex overview
This PR focuses on updating the function used to verify wallet signatures in the `smart-wallet-integration.test.ts` file. The change improves clarity by renaming `checkContractWalletSignature` to `verifySignature` and modifies the way the contract is obtained.

### Detailed summary
- Renamed the function from `checkContractWalletSignature` to `verifySignature`.
- Changed the way the contract is constructed by removing the `getContract` call and directly using the parameters `address`, `chain`, and `client`.
