[SDK] Refactor: More Viem to Ox migration (#5790)

TOOL-0000

<!-- start pr-codex -->

---

## PR-Codex overview
This PR focuses on migrating functionality in the `thirdweb` package from `viem` to `ox`, improving consistency and possibly performance. It updates various files to utilize `ox` components, enhancing the codebase's integration with the `ox` library.

### Detailed summary
- Migrated `maxUint256` imports from `viem` to `ox/Solidity` in multiple files.
- Updated the `isErc6492Signature` function to use `ox__Hex.slice`.
- Changed `decodeAbiParameters` to `ox__AbiParameters.decode`.
- Replaced various utility functions with their `ox` equivalents across different modules.
- Enhanced the `verifyHash` function to utilize `ox__Signature`.
- Added new tests for `verifyContractWalletSignature` using `smartWallet`.
- Updated the workflow file to include new pull request types.
