feat: add model type mappings for cloud custom nodes

Add mappings for model directories used by cloud-deployed custom nodes:
- FlashVSR, SEEDVR2 (video upscaling)
- depthanything (depth estimation)
- latent_upscale_models (latent upscaling)
- sam2, sams, ultralytics (segmentation)
- nlf (other)

These mappings enable the "Use" button in the model browser to create
the correct loader node when users click on models in these directories.
