Error Handling Strategy

1. Model Validation: Checks ModelState.IsValid before processing requests
2. Try-Catch Blocks: Wraps operations in exception handlers
3. User Feedback: Uses TempData for error messages in views
4. Status Codes: Returns appropriate HTTP status codes (404, 500)
5. Graceful Degradation: Returns empty lists instead of error pages when listing fails
