feat: add model-to-node mappings for CogVideo, inpaint, and LayerDiffuse (#9890)

## Summary
- Add `quickRegister()` entries for 3 model directories missing UI
backlinks:
- `CogVideo` → `DownloadAndLoadCogVideoModel` (covers CogVideo,
CogVideo/ControlNet/*, CogVideo/VAE)
  - `inpaint` → `INPAINT_LoadInpaintModel`
  - `layer_model` → `LayeredDiffusionApply`

These mappings ensure the "Use" button in the model browser correctly
creates
the appropriate loader node when users click on models from these node
packs.

## Test plan
- [ ] Verify "Use" button works for CogVideo models in model browser
- [ ] Verify "Use" button works for inpaint models (fooocus, lama, MAT)
- [ ] Verify "Use" button works for LayerDiffuse models
