Update project structure and dependencies

Key features implemented:
- Updated .gitignore to include comprehensive ignore patterns for multiple languages and build artifacts
- Removed auto-score related components and routes from ContentArea, Sidebar, mobile navigation, and preload types
- Deleted AutoScoreManager, Rule builder, and associated service/engine files
- Updated Settings component to remove auto_score_enabled setting handling
- Cleaned up type definitions and navigation configurations to reflect feature removal

The changes streamline the project by removing the auto-scoring feature while maintaining core functionality and improving project organization through updated ignore rules.
