Allow args as bytes for SC interactions

[popenta]

If the Abi file is not provided to the factory/controller, the function's arguments can be passed as an array of bytes. The args are considered properly formatted, converted to their hex representations and passed to the function.

Pull Request Overview

This PR adds support for passing smart contract function arguments as raw bytes (Buffer or Uint8Array) when an ABI file is not provided. The factory now detects byte array arguments, converts them to their hex representation, and includes them in the transaction data.

Key changes:

• Added buffer argument detection and conversion logic in the SmartContractTransactionsFactory
• Added comprehensive test coverage for both TypedValue and byte array arguments
