fix: set-state via call

[mkundu1]

Context

There was an issue in the previous PR that implemented parameter set-state via __call__ as the value was not sent to Fluent in the expected format.

Change Summary

Only the first argument value is sent to Fluent while setting parameter state via __call__.

Rationale

To send the set-state value to Fluent in the correct format

Impact

New unittest has been added, the example script exhaust_system_settings_api.py will pass.

Pull Request Overview

This PR fixes an issue with setting parameter state via the __call__ method, ensuring that values are sent to Fluent in the correct format. Previously, when using keyword arguments with __call__, the entire dictionary was being passed to set_state, but Fluent expected only the value.

Key changes:

• Modified __call__ in the base class to extract only the first value from kwargs before passing to set_state
• Added __call__ method override in a child class to handle kwargs differently
• Added test coverage for the set-state-via-call functionality
