🧪 [testing improvement] Add missing error path tests for products list

[cmuench]

🧪 What: The testing gap addressed involves missing error path test coverage for various list commands (listProductMediaAction, listProductTypesAction, listProductAttributesAction, listProductAttributeTypesAction, listProductLinkTypesAction) in lib/commands/products-actions.js as well as fixing flawed assertions (expect(jest.spyOn(console, 'error')).toBeDefined()) in the test suite that didn't truly verify if errors were being handled.\n📊 Coverage: Test coverage for lib/commands/products-actions.js was improved from ~95% statements and 82% branch to ~99% statements and 83% branch coverage. Specific scenarios tested are the error paths where mockClient.get.mockRejectedValue simulates network errors.\n✨ Result: A more robust and reliable test suite that effectively captures error-handling behaviors for product list operations.
