Paid Scenes Voxta Beta Scene

1. Added Delete chat button.
2. Fixed dependency issues.

Meet Adam, our latest fully mocapped character in the Voxta Beta scene!

1) Added a new character model from the video preview.
2) Added a button to enable/disable subtitles.
3) Improved lip sync for more natural and accurate mouth movements when character talk.
4) For the sake of simplicity, Voxta State and Voxta Actions have been replaced. Now, instead of VxA and VxS, it's just VA and VS.
5) Made small animation fixes and improvements.

Note: Please ignore the 'cheesyFX HeelAdjust' error; it doesn't affect anything.
