e76406d3 - Drop LTX2DFRCoreMixin in favor of # Copied from

Drop LTX2DFRCoreMixin in favor of # Copied from Each DFR pipeline now owns pack/unpack, prepare_latents, and denoise so the classes stay self-contained. Shared helpers copy from LTX2Pipeline / LTX2ConditionPipeline, and DFR-specific methods copy from LTX2DFRPipeline. dfr_core.py keeps only the constants and canvas helpers.
