Pull Request Overview

This PR fixes a bug in the ConfigRegistry copy constructor by ensuring that the new registry is properly initialized with a deep copy of the configurations from the original registry.

• Updates the iteration in the copy constructor to use the original registry's configurations ("that.configs")
• Ensures that each configuration is deep copied via createCopy() and re-registered to the new registry

• The updated loop now iterates over 'that.configs.entrySet()', which correctly copies from the original registry. Ensure that the deep copy provided by createCopy() meets all requirements for registered configurations.
