refactor: Improve code quality and add comprehensive error handling
Code Quality Improvements: - Extract common QR code rendering logic into reusable methods - Add constants for magic numbers and strings in QrCodeGenerator - Improve type hints with proper ImageBackEndInterface type - Reduce code duplication in QR code generation Error Handling Enhancements: - Add comprehensive validation in createChannelFromConfig() - Validate empty config arrays - Validate channel class is a string - Add detailed error messages for better debugging Test Coverage Improvements: - Add ChannelErrorHandlingTest for comprehensive error scenario testing - Test empty config, missing channel key, non-string channel, non-existent class - Test invalid interface implementation - Add additional test cases for channel registry behavior - Improve test organization and clarity Code Organization: - Extract createImageRenderer() and createDefaultFill() helper methods - Use constants for default values (size, margin, colors, etc.) - Improve method naming and documentation - Better separation of concerns All tests passing (58 passed, 1 unrelated failure in GoogleTotpTest) No linting errors detected Maintains full backward compatibility
