Handle nested data objects in RemoteTool and ApiCallStep

Description:

Currently, the RemoteTool and ApiCallStep components in WayFlow accept a data parameter that is limited to simple data types. This limitation restricts the ability to pass complex data structures, such as nested dictionaries or lists, which are often necessary for advanced use cases. As a result, developers are forced to implement workarounds, leading to less efficient and harder-to-maintain code.

Steps to Reproduce:

1. Attempt to pass a nested dictionary or list as the data parameter to a RemoteTool or ApiCallStep instance.
2. Observe that the component does not handle the complex data structure as expected, resulting in errors or unexpected behavior.

Expected Behavior:

The RemoteTool and ApiCallStep components should support complex data structures in the data parameter, allowing developers to pass nested dictionaries, lists, and other complex types without encountering errors.

Start by locating the RemoteTool and ApiCallStep component definitions and the code handling their data parameters. Trace how nested dictionaries and lists are currently processed, then verify that both components accept these structures without errors or unexpected behavior.
