Add comprehensive quiz system with leaderboard integration
 TASK COMPLETION SUMMARY: Models Added: - Quiz: Track quiz sessions with category, scoring, and completion status - QuizQuestion: Track individual questions and user answers with ordering - UserScore: Store best scores per category with leaderboard functionality - Folder: File management system integration Quiz System Features: - 15 questions per category (5 easy, 5 medium, 5 hard) with random selection - Category-based quizzes: crypto, network, web, general, python, etc. - Difficulty-based question selection and scoring (10/20/30 points) - Real-time progress tracking with visual progress bar - Timer functionality with visual countdown - Best score tracking per category with automatic updates Views Implemented: - start_quiz: Initialize new quiz with proper question selection - take_quiz: Interactive quiz interface with progress tracking - submit_quiz_answer: Real-time answer processing and scoring - quiz_results: Comprehensive results with difficulty breakdown - leaderboard: Top 10 scorers per category with rankings 1-10 Templates Enhanced: - Interactive quiz interface with timer and progress bar - Responsive design with difficulty badges and point display - Fixed template syntax using 'widthratio' filter (not 'mul') - Real-time score updates and navigation integration Integration Features: - User scores display in navigation bar via context processor - Leaderboard with category-based rankings and user comparisons - Automatic score saving on quiz completion - No unique constraint on Quiz model (allows multiple attempts) - Comprehensive error handling and debug logging Migration Management: - Single migration file approach (0001_initial.py) - All quiz models integrated into existing migration - No multiple migration files created - Database schema properly maintained Additional Enhancements: - Sample challenge creation command for testing - Timer integration with visual feedback - Progress tracking with percentage completion - Score persistence and leaderboard updates - Category-based challenge filtering All task requirements fulfilled with proper implementation!
