Enhance CDN File Error Handling and Response Utilities

Description

Summary of Work

This pull request introduces a robust error handling system for our CDN file service, focusing on improving error management, response consistency, and code reliability.

Our goal is to create a centralized, type-safe error handling mechanism that provides clear, informative responses while maintaining flexibility for different error scenarios. This implementation will help developers and users better understand and manage file-related errors in our CDN service.

Changes Made

Error Handling Improvements:

• Implemented custom FileAccessError for granular file permission handling
• Created centralized error response utility with standardized error types
• Added comprehensive error logging mechanism with contextual information

Architectural Enhancements:

• Introduced type-safe TypeScript error handling in fileErrorHandler
• Developed flexible error response generation utility
• Established consistent error response format across the service

Utility Capabilities:

• Support for multiple error types (NOT_FOUND, FORBIDDEN, INTERNAL_SERVER_ERROR)
• Ability to add custom error messages and additional details
• Standardized error logging with timestamp and context tracking

Tests and Verification

Test Coverage Verification:

• Added comprehensive unit tests for error response utility
• Verified error type handling and response generation
• Tested edge cases including invalid error types
• Ensured consistent behavior across different error scenarios
• Maintained 100% test coverage for error handling utilities

Test Scenarios Covered:

• Standard error response generation
• Custom error message handling
• Additional error details integration
• Error type fallback mechanisms
• Logging utility functionality
