* prevent (Managed by Forge) settings reverting to default
* save CLIP skip to config when changed, inconsistent / unpredictable saving behaviour otherwise
* make unload_model_weights do that
* rename Settings > Actions > unload checkpoint button to 'Unload all models'
* remove (comment out) reload button, as it does nothing and is unlikely to ever do anything since models are loaded on demand
Allows setting of preferred VAE and Text encoder(s) for checkpoints when selected via Checkpoint cards. No selection saved means no change to current toprow setting. 'Built in' option, if the only choice, means clear the toprow selection (therefore use vae/te built-in to checkpoint).
Also allows setting model type for checkpoints (SD1/SD2/SDXL/Flux/Unknown) (user set only, no attempt at autodetection), enabling filtering of the cards based on UI preset.
