fix(web-test): reduce smart TTS wait from 100ms/char to 70ms/char

Browse Source 
Measured real Edge TTS (ru-RU-DmitryNeural) durations:
  57 chars → 4.4s (77ms/char)
  72 chars → 6.0s (84ms/char)
  126 chars → 8.2s (65ms/char)
  745 chars → 48.0s (64ms/char)

Old 100ms/char overestimated by 30-55%, causing long silent pauses
after speech in showImage/showTitleSlide/showCaption. New 70ms/char
gives ~10% safety margin without excessive silence.
