d961a388 - fix(image_processor): maintain 3-tuple return contract in InpaintProcessor.preprocess when mask is None (#14481)

fix(image_processor): maintain 3-tuple return contract in InpaintProcessor.preprocess when mask is None (#14481) fix(image_processor): preserve 3-tuple return contract when mask is None (#14470) Ensure InpaintProcessor.preprocess returns (image, None, postprocessing_kwargs) when mask is None, preserving the expected 3-tuple return contract and signature consistency across all preprocess branches. Consolidate unit tests into a parameterized test covering with-mask, without-mask, and crop configurations.
