feat(14-03): convert auth/oauth/csv services to async, await seedDefaults

- auth.service.ts: 10 functions async, removed .all()/.get()/.run()
- oauth.service.ts: 7 functions async, boolean conversion (used: true/false)
- csv.service.ts: export/import functions async, removed .all()/.get()/.run()
- server index.ts: seedDefaults() now awaited for async DB
- PGlite smoke test confirms async services work end-to-end
