fix: Suppress IDE warning for optional pytorch_i3d import

- Added type: ignore comment for optional pytorch_i3d import
- Removed unused typing imports (Optional, List, TYPE_CHECKING)
- FVD works with simplified I3D by default
- Full I3D is optional (install from GitHub if needed)

Resolves IDE import warning while maintaining functionality.
