Fix Kokoro TTS integration - correct KPipeline API

- Removed model_path parameter (not supported by kokoro package)
- Removed repo_id parameter (causes KeyError)
- Use default KPipeline initialization with only lang_code
- Kokoro package handles model download automatically

Tested and working:
- American English voices (alloy, af_sarah, am_michael, etc.)
- British English voices (bm_george, bf_emma, etc.)
- Audio generation produces valid MP3 files
