refactor: streamline authentication workflows and remove deprecated services

- Removed WhmcsLinkWorkflowService and integrated its functionality into new AccountCreationWorkflowService and AccountMigrationWorkflowService.
- Introduced OtpEmailService for sending OTP emails, enhancing email handling in LoginOtpWorkflowService and VerificationWorkflowService.
- Replaced NewCustomerSignupWorkflowService and SfCompletionWorkflowService with AccountCreationWorkflowService, consolidating account creation logic.
- Updated GetStartedCoordinator to utilize new workflow services, improving clarity and maintainability of the authentication process.
- Enhanced error handling and logging across workflows to provide better feedback during account creation and migration.
