fix: remove manual edits from generated code to match CI/CD expectations

The generator's simple approach for SSH bulk-mode works correctly - setting
child values on presence containers automatically creates the parent container.
Manual edits to generated files caused CI/CD failure as the generator
regenerates all code from templates during the build process.

This commit removes the manual 'atomic' logic and trusts the generator,
ensuring CI/CD validation passes.
