fix(FastAPI): use popupdate when [un]voting

Browse source 
The `aurweb.scripts.popupdate` script is used to maintain
the NumVotes and Popularity field. We could do the NumVotes
change more simply; however, since this is already a long-term
implementation, we're going to use it until we move scripts
over to ORM.
