fix(download): accept UNet and Diffusion Model file types from CivitAI

Browse Source 
- Prefer file type (UNet/Diffusion Model) over baseModel name when
  deciding whether a checkpoint routes to the unet folder
- Add UNet to backend primary file type whitelist
- Add Krea 2 to DIFFUSION_MODEL_BASE_MODELS
- Include UNet/Diffusion Model files in frontend file selection UI
- Use actual file type from CivitAI in download params instead of
  hardcoded 'Model'
