[FIX]: Conditional proxy setup for frontend development

[jaseemjaskp]

Summary

This PR fixes an issue in the frontend development setup where the proxy middleware would attempt to initialize even when no backend URL is configured, potentially causing development server startup issues.

Changes

• Modified to conditionally set up the proxy middleware only if environment variable is provided and not empty
• Added validation to check if the environment variable exists and is not just whitespace

Motivation

The previous implementation would always attempt to create a proxy middleware regardless of whether a backend URL was configured. This could lead to:

• Development server startup issues when is not set
• Potential proxy configuration errors in development environments where backend is not available
• Better separation of concerns between frontend-only development and full-stack development

Related Issues

This change improves the frontend development experience by making the proxy setup more robust and conditional.

Testing

• Tested with set - proxy works as expected
• Tested without - no proxy is created, frontend starts without issues
• Tested with empty - no proxy is created

Type of Change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation update

Checklist

• Code follows the project's style guidelines
• Self-review of the code has been performed
• Changes have been tested locally
• No breaking changes introduced
• Frontend development setup works with and without backend URL configuration
