fix: rebuild SVD workflow with correct node types

- Replace DiffusersLoader with ImageOnlyCheckpointLoader
- Replace SVDSampler with SVD_img2vid_Conditioning + KSampler
- Add VideoLinearCFGGuidance for temporal consistency
- Add all node connections in links array
- Configure VHS_VideoCombine with H.264 parameters
