📌 Pull Request Title

Description

Created a Track granular lesson engagement per user, including time spent and quiz performance. Expose backend endpoints to retrieve analytics for dashboards or profile pages.

Created module: analytics.module.ts, analytics.service.ts, analytics.controller.ts.

Track:
lesson_start_time, lesson_end_time (calculate duration).
Quiz score per attempt.

Implemented the following endpoints:
POST /analytics/lesson-start
POST /analytics/lesson-end
POST /analytics/quiz-score
GET /analytics/user/:userId

Used decorators to auto-fetch user from JWT.
Ensured analytics data is stored efficiently (via new lesson_analytics and quiz_analytics entities).

Testing:
Wrote Unit tests for duration and score tracking logic.
Integration tests for each endpoint.
Performance test for GET /analytics/user/:userId with multiple lessons.
