feat: Add smart-local-wallet-sdk-v4.test.ts

This commit adds the smart-local-wallet-sdk-v4.test.ts file, which contains tests for creating a local smart backend wallet and sending SDK v4 transactions. The tests deploy an ERC20 token, mint tokens, and check the balance. This change improves the test coverage for the smart backend wallet functionality.
