fix(15): convert auth service/tests to async PGlite pattern

The executor agents wrote sync SQLite-style calls (.get(), .all(), .run())
instead of the async Postgres pattern established in Phase 14. Fixed:
- auth.service.ts: use await + destructuring for all DB operations
- auth routes: await listApiKeys
- All auth test files: async createTestDb(), await service calls
