get_model_info again skips model_index.json resolution entirely when
override_pipeline_cls_name is set, so overrides keep working for local
checkpoints without a diffusers model_index (and trigger no downloads).
Replace the nine copy-pasted kandinsky5 detectors with a parameterized
factory (identical matching semantics) and add a dedicated I2V Lite distilled
entry + preset so those checkpoints get distilled sampling defaults
(guidance 1.0 / 16 steps) instead of the sft fallback's 5.0 / 50.
