Update Scenes' 'Updated At' Date on Heatmap Gen & Expand Error Log

The UpdatedAt field of a scene is now correctly updated after Generate Task is run and a heatmap linked to a scene.. I thought it made more sense here in the generate heatmap compared to scan.go, owing to funscript data not being tracked/stored in a typical sense with the scan message "updating metadata".
I used a simplified error messaging as I did not think it was critcal but I do not know if did not use the correct code structure
If updating the UpdatedAt field should be done there when the file is marked as interactive I can try and do that?
This would fix this long-standing issue #3738

The error message change is useful as I could not tell which scripts were causing errors before but now it is clear in the logs
