UI Tweak - move 'model' and 'loras' into the main panel of Presets

[johnbrownlow]

This is a very small tweak, but when creating a new preset, the 'model' is hidden under 'Display normally-hidden options', which took me ages to find out. It feels like it should be front and center in the Preset as it's such an integral part of the workflow (and this option is NOT normally hidden in the interface... in fact it's always visible!)

This would have the benefit of making it much easier to create grids which compare different model types (eg Flux vs SD3.5, lightning vs turbo vs whatever).

The same is true for 'Loras', since when creating grids it's relatively tricky to swap in and out loras (you have to use the technique in the prompt and then use a prompt replace to cycle through them.

I realize it's trivial to show the normally-hidden options but it's taken weeks for me to discover this!!
