. Add `POST /api/v1/quizzes/:id/feedback` endpoint

[DeFiVC]

What: Add an endpoint that allows users to submit feedback on quiz questions (e.g., "this question is unclear", "wrong answer marked as correct").

Why: Quiz quality depends on user feedback. Without a feedback mechanism, bad questions persist and harm the learning experience.

Scope: Create quiz_feedback table with quiz_id, question_id, user_id, type (unclear/wrong/other), comment, created_at. Add endpoint that accepts feedback and stores it. Admin can review feedback to improve questions.

Acceptance criteria:

• Users can submit feedback on specific questions
• Feedback includes type and optional comment
• Duplicate feedback from same user is prevented
• Admin can view feedback summary per question

Technical context: src/modules/quizzes/quiz.service.ts — quiz operations. src/database/schema.ts — schema definitions.
