feat(14-04): convert auth, OAuth, settings routes and auth middleware to async/await

- Add await before all service calls in auth, OAuth routes
- Convert settings.ts direct DB calls: remove .get()/.run(), use await + destructuring
- Auth middleware: await getUserCount, getSession, refreshSession
- Fix formatting in threads.ts for biome compliance
- All files pass lint
