Bugfix: regenerated FX layers now work on uploaded avatars

VRChat won't update the FX layer associated with an avatar unless its
GUID changes. Delete the GUID file when overwriting our generated FX
layer to work around this.

* Change paging behavior: when a region is updated, we re-page everything
  that comes after it. This fixes the issue where we go back to update
  something, then jump back to the current screen, leaving some random
  chunk of text somewhere on the board.
* Reduce transcription time from 28s to 10s. I'm going to expose this to
  the user since there's a fundamental latency/stability tradeoff here.
