Ideogram4 workflows error with "NotImplementedError: The operator 'aten::_int_mm' is not currently implemented for the MPS device."

### Custom Node Testing

- [x] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

Using the official Ideogram4 text to image workflows should work on modern Apple devices (e.g. M5 Max in my case).

### Actual Behavior

The workflows crash with the below error

### Steps to Reproduce

- Use the official ideaogram4 text to image workflow (the int8 one for example).
- Let Comfy download the missing models.
- Run the workflow.

### Debug Logs

```powershell
Node threw an error during execution.

# ComfyUI Error Report
## Error Details
- **Node ID:** 98:12
- **Node Type:** SamplerCustomAdvanced
- **Exception Type:** NotImplementedError
- **Exception Message:** NotImplementedError: The operator 'aten::_int_mm' is not currently implemented for the MPS device. If you want this op to be considered for addition please comment on https://github.com/pytorch/pytorch/issues/141287 and mention use-case, that resulted in missing op as well as commit hash 7269437d655783a26cba32aa88195b741ff496aa. As a temporary fix, you can set the environment variable `PYTORCH_ENABLE_MPS_FALLBACK=1` to use the CPU as a fallback for this op. WARNING: this will be slower than running natively on MPS.

NotImplementedError: The operator 'aten::_int_mm' is not currently implemented for the MPS device. If you want this op to be considered for addition please comment on https://github.com/pytorch/pytorch/issues/141287 and mention use-case, that resulted in missing op as well as commit hash 7269437d655783a26cba32aa88195b741ff496aa. As a temporary fix, you can set the environment variable `PYTORCH_ENABLE_MPS_FALLBACK=1` to use the CPU as a fallback for this op. WARNING: this will be slower than running natively on MPS.

### Other

_No response_

Reproduce the official Ideogram4 int8 text-to-image workflow on an Apple MPS device and start at comfy/ldm/ideogram4/model.py, especially the _backbone and _run_conditional path shown in the trace. Trace where aten::_int_mm is reached and check the reported PyTorch MPS limitation. Done means the workflow completes without this NotImplementedError, with behavior verified using the same reproduction steps.
