fix: address QA feedback on PR #2

- Fix test mock paths from "./db" to "../db" to match route imports
- Add "test" back to build job needs array (regression from previous PR)

This addresses QA feedback:
1. Test job missing DATABASE_URL - fixed by correcting mock paths so tests use mocked db instead of trying to connect to real DB
2. Build job dropped test from needs - restored to prevent building with broken tests
3. Docker push permission denied - requires CTO escalation for GHCR org config
