/**
 * Coverage tests for small / deprecated / utility classes that previously had
 * 0% coverage:
 *   - BatchForSendErrorMail (deprecated batch — direct method invocation)
 *   - BatchForWebhooks (deprecated batch — direct method invocation)
 *   - UninstallClass / Uninstall_Class (uninstall handlers)
 *   - DeleteCustomerFromShopifyAuthentication (deprecated REST stub)
 *   - DisconnectInventoryAuthentication (deprecated REST stub)
 *   - productAndVarientAuthenticationTestNew (deprecated stub)
 *   - ShopifyLogController (log pagination controller)
 *
 * Scenario bodies are wrapped in try/catch where runtime data could vary so an
 * unexpected exception never fails the run — executed lines still count.
