Fix Save Refinement Latent not executing + decouple motion floor from liked_dir

OUTPUT_NODE = True forces ComfyUI to run the node even with no downstream
connection on the LATENT output. Motion floor now activates as soon as
embed_guidance is on and a refinement key is set, independent of liked_dir.
