fix: correctly save and load configs in UI

[marginal23326]

• Fixed saving UI configs (previously, it would only save the default configs).
• Fixed to correctly set the model name in the UI from the config even when it's a custom one.

def save_current_config(self, *component_values):
I think we do not need to input component_values to save_current_config fn and we should use components saved in config_manager, because the value of components may change during using.

updated the logic to use the manager's state directly; it should be alright now.
