perf(stt): default Whisper model small -> medium for better Korean accuracy

Whisper 'small' frequently mis-transcribes Korean (esp. the wake word 자비스:
'아비스', '자 비싸'). STT is only ~0.1s warm so there is ample latency headroom;
'medium' is far more accurate and fits VRAM alongside qwen2.5:3b on the 8GB GPU.
