Sampling window: model-specific defaults and entry fields

[O-J1]

1. Hide scheduler aka sampler for flowmatching models as its ignored by them
2. Hide video fields for image models
3. Hide inpainting fields where not an inpainting model
4. Add cfg, steps, width, height and negative prompt to SampleConfig based on model type. Ensuring we dont screw users over from the start. Only Chroma utilises a negative prompt currently.

Yes, actually I forgot to mention it also only shows inpainting fields for inpainting models. So it covers everything
