Complex types are unsupported on MPS

Nobody has claimed this yet.

I'm trying to use inpaint+lama and get the following error during preview:

Reproduce the inpaint+lama preview and image-generation paths on the reported MPS setup. Start at extensions-builtin/sd-webui-controlnet/annotator/lama/saicinpainting/training/modules/ffc.py:86, where torch.fft.rfftn raises the reported error, and trace how that path is reached from the ControlNet preprocessor. Done means both reported operations no longer fail with the MPS complex-type error.
