refactor: update Quiz schema and Prisma types for enhanced data structure

- Replaced existing score and answers fields in the Quiz schema with more descriptive fields: numberOfCorrectAnswers, numberOfIncorrectAnswers, numberOfQuestions, correctPoints, totalPoints, and userInput.
- Updated the PrismaTypes interface to remove the questions relation and streamline the data model, ensuring better clarity and maintainability.
- Updated the subproject reference in the epess-database to the latest commit for consistency in project dependencies.
