Refactoring: Feature-Based Directory Structure

Changes

• Refactored to a feature-based directory structure
• Moved non-shared components and actions into feature directories
• Used Next.js bracketed directory to organize code without affecting URL paths

New Directory Structure

Benefits

1. Separation of concerns: Related files for each feature are grouped together
2. Scalability: Easier to extend when adding new features
3. Discoverability: Easier to find code related to specific features
4. Feature independence: Features can be maintained and developed independently
