fix: complete ComfyUI workflow schema validation

Fix all 20 production workflows to comply with ComfyUI schema requirements:
- Add missing 'flags', 'order', 'mode', 'properties', 'size' fields to all nodes
- Update deprecated node names:
  - AnimateDiffLoader → AnimateDiffLoaderV1
  - VHSVideoCombine → VHS_VideoCombine
  - IPAdapterApply → IPAdapter
  - IPAdapterApplyFace → IPAdapterFaceID
- Remove deprecated nodes: PreviewVideo, SaveVideo
- Add fix_workflows.py script for future maintenance

Changes:
- 16 workflows updated with complete schema
- 4 workflows (FLUX, SD3.5) were already valid
- All workflows now pass zod schema validation
