Write the real DPMSolverMultistep config
Browse filesscheduler_config.json said `UniPCMultistepScheduler` while model_index.json said `DPMSolverMultistepScheduler`, so it loaded as DPM carrying UniPC's field set. The pipeline now samples with `self.scheduler` instead of constructing its own, so the file has to be correct. The resulting scheduler is bit-identical -- same timesteps, same sigmas -- to the one the old `flow_solver='dpm'` branch built.
