Rob Mulholand d496dad33c Decouple log extraction from transformer delegation
- limit missing headers results set to 100 so that extraction doesn't
  excessively block delegation
- wrap checked headers functions in repository struct
- move storage repository to factory, to correspond with event
  repository path
- remove unused files
- reformat sql
- remove line breaks in imports
