feat(14-03): convert core data services to async PostgreSQL operations

- item.service.ts: 6 functions async, removed .all()/.get()/.run()
- category.service.ts: 4 functions async, transaction uses async callback
- thread.service.ts: 10 functions async, transactions in resolveThread/reorderCandidates use async callbacks
- setup.service.ts: 8 functions async, syncSetupItems transaction uses async callback
- totals.service.ts: 2 functions async, removed .all()/.get()
