Fix ImportError with newer Kornia versions (missing pad import)

[CozzyTyler]

With recent versions of kornia, the following import fails:

from kornia.geometry.transform.pyramid import pad

This prevents the entire node package from loading:

ImportError: cannot import name 'pad' from 'kornia.geometry.transform.pyramid'

A simple fix is:

 import torch.nn.functional as F
+pad = F.pad

 from kornia.geometry.transform.pyramid import (
     PyrUp,
     build_laplacian_pyramid,
     build_pyramid,
     find_next_powerof_two,
     is_powerof_two,
-    pad,
 )

After this change the nodes load correctly with current Kornia versions.

Environment:

• Linux (Arch)
• Python 3.14
• Latest ComfyUI
• Latest ComfyUI-LTXVideo

It works for me! Tx a lot.

I changed:
from kornia.geometry.transform.pyramid import (
PyrUp,
build_laplacian_pyramid,
build_pyramid,
find_next_powerof_two,
is_powerof_two,
pad,
)

to:

from kornia.geometry.transform.pyramid import (
PyrUp,
build_laplacian_pyramid,
build_pyramid,
find_next_powerof_two,
is_powerof_two,
)
