Feature/whz/fix api only mode lora nowork

Remove deprecated style method

- correctly read values from pasted infotext
- setting for column count
- infotext paste: do not add a field to override settings if some other component is already handling it

Git autofix

Clean up k-diffusion sigma params

- the setting for preferring opts.sd_vae has been inverted and reworded
- resolve_vae function made easier to read and now returns an object rather than a tuple
- if the checkbox for overriding per-model preferences is checked, opts.sd_vae overrides checkpoint user metadata
- changing VAE in user metadata  for currently loaded model immediately applies the selection

add proper support for recalculating conds in k-diffusion samplers
remove support for compvis samplers

add explicit content-type header for image/webp

Add missing k-diffusion sigma params to infotext
