Overview

This pull request enhances the quiz experience by introducing a quiz completion celebration sound. The sound is triggered only after a user successfully completes the final question, providing positive auditory feedback and reinforcing the platform's gamification experience.

The implementation has been designed to integrate seamlessly with the existing architecture without affecting the current quiz flow, UI, scoring, navigation, or application behavior.
