Proposed resolution

• Update the UI logic to show all code components, not just those with status: false
• Remove tests/modules/xb_internal_code_components, because it is now obsolete (it was necessary to get anything to show up at all). Instead, update at least one code component in tests/modules/xb_test_code_components/config/ to have status: false. xb_test_code_components_with_no_props
