feat: aprimorado o preview de falantes na tela Refinar para reprod

- aprimorado o preview de falantes na tela Refinar para reproduzir os trechos do vídeo
- corrigida a leitura dos timestamps do preview de falantes usando os clipes do banco
- alterado o preview de falantes para reproduzir diretamente na timeline ativa do Premiere
- evitadas reinicializações concorrentes durante o monitoramento do preview na timeline
