feat: enhance error logging for better debugging of JSON parsing issues

Browse Source 
- Add comprehensive error logging in mirror-repo API endpoint
- Enhance HTTP client error handling with detailed response information
- Improve concurrency utility error reporting with context
- Add specific detection and guidance for JSON parsing errors
- Include troubleshooting information in error responses
- Update tests to accommodate enhanced logging

This will help users diagnose issues like 'JSON Parse error: Unexpected EOF'
by providing detailed information about what responses are being received
from the Gitea API and what might be causing the failures.
