Subject: [PATCH 1/2] feat: infer-web: Implement infer_loaded_voice API
 endpoint

Implements the 'infer_loaded_voice' API endpoint to allow external clients to query
the model loading status.

- Adds a hidden Gradio button and JSON output component bound to the API name
  "infer_loaded_voice" for client access.
- Corrected the usage of i18n() for Gradio labels to use English keys, ensuring
  internationalization compatibility.
- This endpoint returns the currently loaded model ID, significantly improving
  reliability and user experience for external tools.

Subject: [PATCH 2/2] feat: modules: Add state variable to track loaded model
 ID

Adds a state variable 'self.loaded_model_id' within the model loading logic in modules.py.

This minimal change is necessary to persistently track which model has been loaded.
It enables the new API endpoint in infer-web.py to report the current model status
to the client, which is crucial for preventing premature inference errors.
