[FEATURE]: Avoid silent recording stop when LLM API is unavailable (no error shown)

[revectores]

📝 Feature Description [Please make everyone to understand it]

Description When the LLM API becomes unreachable (e.g., due to network disconnection or invalid API key), the application silently stops recording without showing any error message or notification. Users may not realize the recording has stopped until checking the history.

Expected Behavior Display a clear error or warning when the LLM API is unavailable. Pause recording gracefully or retry automatically after reconnection. Log a descriptive error entry for debugging. Optionally show an “LLM status” indicator (e.g., red = disconnected).
