MoECalibrationModule bugfix (#2023)

SUMMARY:
Without this bugfix, `examples/awq/qwen3_moe_example.py` errors out with
stack trace:
```

    replacement = MoECalibrationModule.load_from_registry(
TypeError: RegistryMixin.load_from_registry() takes 2 positional arguments but 4 were given
```

This resolves the bug (but subsequently hits another error #2022 )
