Add 1328 native resolution for Qwen Image training (#749)

* Add 1328 native resolution for Qwen Image training

Qwen-Image and Qwen-Image-2512 have a native 1:1 resolution of 1328x1328
as documented in the official model card's aspect ratio table. Adding it
to the resolution buckets and UI allows training at the model's native
resolution for improved quality.

* Revert example config change (24GB OOM at 1328)
