Subject: [PATCH] Fix TTS stop on navigation and answer; set Polly Joanna as
 default

- Add key prop to TTSButton based on question id + answer state
  so component remounts (and audio stops) on both question navigation
  and answer selection in study mode
- Set AWS Polly Joanna (neural) as default TTS voice
