Consolidate Error Handling Utilities for Improved File and API Error Management

Description

Summary of Work

This pull request introduces a comprehensive error handling strategy across our file and API services, focusing on:

1. Standardized Error Responses: Implement a centralized approach to error handling
2. Improved File Access Error Management
3. Enhanced Logging and Error Tracking

Key Improvements:

• Introduced FileAccessError for precise file-related error handling
• Created centralized error response utility with predefined error types
• Added type-safe error logging mechanism
• Improved error context and debugging capabilities

The changes provide a more robust and consistent error handling approach, making it easier to diagnose and respond to various error scenarios in our file and API services.

Changes Made

1. Created FileAccessError class in fileErrorHandler.ts for type-specific file access errors
2. Implemented fileErrorHandler middleware to handle file-related error scenarios
3. Added checkFileAccess utility function for safe file permission checks
4. Developed createErrorResponse function in error-response.js for standardized API error responses
5. Introduced createErrorLog function for consistent error logging
6. Defined ERROR_TYPES enum to centralize error type definitions

Tests and Verification

Verification steps:

1. Unit tests for FileAccessError class
2. Middleware error handling tests for fileErrorHandler
3. Error response generation tests for createErrorResponse
4. Error logging functionality tests
5. Verified error type mapping and status code assignments
6. Checked proper error propagation and handling in different scenarios
