57279: Fix for MNT-9801.
I have very slightly refactored the configuration of thumbnails. Rather than inject system.thumbnail.generate into both CreateThumbnail- and UpdateThumbnailActionExecuter, I am now injecting it into the ThumbnailService centrally. I left the old injector methods for backwards compatibility, but deprecated them.
Now all requests to create a thumbnail via the ScriptNode API pre-check that thumbnail generation is enabled.
