when testing cli add wrapper for invoke method of CliRunner

We use CliRunner from typer library in a way similar to https://typer.tiangolo.com/tutorial/testing/

So for example in test for savings we invoke

    result = runner.invoke(
        cli,
        [
            "process",
            "savings",
            "deposit",
            f"--amount={amount_to_deposit.as_legacy()}",
            f"--password={WORKING_ACCOUNT.name}",
            f"--sign={WORKING_ACCOUNT_KEY_ALIAS}",
        ],
    )

We could have wrapper for this method as we use this very often in multiple scenarios for example smth like process_savings_deposit(cli_with_runner, amount_to_deposit, WORKING_ACCOUNT.name, WORKING_ACCOUNT_KEY_ALIAS)

or

process_savings_deposit(cli_with_runner, amount=amount_to_deposit, password=WORKING_ACCOUNT.name, sign=WORKING_ACCOUNT_KEY_ALIAS)

This will apply not only for savings but for (almost) all cli tests
