Return the shot's start frame image from getShotTableState

Shot Lab was showing the video's single thumbnail next to every shot's
layout. The backend now returns the frame the layout was detected in as
a base64 JPEG (frameImage), selected by the GetShotTableState operation.
Also dedupes ShareLinkGQL/CreateShotShareLinkInput, which appeared twice
in the committed schema after a bad merge.
