Update Action Log cannot render old volume actions with isCompacted=true

[fm3]

Frontend crashed when opening an old annotation’s restore view, because there were updateUserBoundingBoxesInVolumeTracing actions in the log that didn’t have the boundingBoxes field. Those actions were compacted and were correctly marked as such (isCompacted=true).

We should figure out how to show these actions in the version restore view.

• should earliestAccessibleVersion have been set?
• should those actions be handled by the frontend at all?

This is a follow-up issue for #7839
