Implements Deen-Bridge#189: course quizzes with MCQ questions, server-side scoring, pass/fail thresholds, attempt history, and lesson completion on passing. Adds: - Quiz and QuizAttempt Mongoose models with repositories - QuizService (create/update/delete/attempt scoring/results) - REST controllers + routes mounted at /api/quiz* (management restricted to verified educators/admins; attempts for authenticated learners) - 11 acceptance tests (scoring spoof-proofing, pass->lesson completion, learner/owner authorization, attempt history) Also includes minimal base boot fixes required for CI (npm test) to pass on the broken upstream/main import graph: migrated missing user preferences runtime modules (preferences.js, UserPreferences.js, preferences.socket.js) from the unwired .ts stubs.

- coreFlows.test.js: the spawnSync app-import child never exited because importing app.js starts job schedulers that keep the process alive, deadlocking the suite indefinitely. Have the child self-terminate after the import resolves (exit 0) or on error (exit 1). - certificate.test.js: correct stale assertion; the certificate service generates 'cert_'-prefixed ids, not 'CERT-'. These are pre-existing issues in the base suite (unrelated to the quiz feature) that were unmasked by the boot fix and prevented the CI Run Tests job from reaching a conclusion.

Closes #189
Summary
Adds a quiz/assessment system for courses. Educators can create/edit/delete quizzes composed of multiple-choice questions with a pass/fail score threshold. Learners can attempt a quiz, get server-side scored results, view their attempt history, and automatically complete the associated lesson when they pass.

Includes a minimal base boot fix (migrated missing user-preferences runtime modules from unwired .ts stubs) that is required for CI (
npm test) to boot the app at all on upstream/main.
