feat(widgets): add Description tab to LoraInfoWidget with dual-mode rendering support

- Add Notes/Description tab switching with tab state persistence in widget value
- Lazy-load model description and version description from /lm/loras/metadata
- Render CivitAI HTML descriptions inline via v-html
- Auto-fetch description when LoRA selection changes while on Description tab
- Fix Vue mode height containment via contain:layout size (lm-vue-node class)
- Fix scroll wheel isolation: widget scroll vs canvas zoom in both render modes
- Add docs/comfyui-dual-mode-widgets.md with widget rendering patterns
