Add new POST endpoint `/api/lm/example-images/set-nsfw-level` to allow updating NSFW classification for individual example images. The endpoint supports both regular and custom images, validates required parameters, and updates the corresponding model metadata. This enables users to manually adjust NSFW ratings for better content filtering.
Add initialization tracking to prevent multiple event listener attachments
in context menu components. Use dataset.initialized flag to ensure NSFW
selector events are only set up once per component instance.
In ModelContextMenuMixin, replace DOM elements and reattach event listeners
to avoid duplicates when components are reinitialized. This fixes issues
where multiple click handlers could be attached to the same elements.
refactor: consolidate model API client creation into a factory function for better maintainability
feat: implement move operations for LoRAs and handle unsupported operations for Checkpoints and Embeddings
