Remove info logs and unused import per PR feedback

- Remove unused Mapping import
- Remove info logs at initialization (connection params)
- Remove info logs in _handle_transcription (transcript details, text sent to LLM)
- Remove info logs in _build_ws_url (WebSocket URL and params)
- Keep debug logs (less verbose, appropriate for development)
