fix(ui): make autocomplete text widget scrollable in Nodes 2.0 mode

In Vue/Node 2.0 mode, the AutocompleteTextWidget's textarea wheel events were intercepted by TransformPane @wheel.capture before reaching the @wheel handler, causing canvas zoom instead of text scrolling.

- Add lm-wheel-scrollable class in Vue mode to hook into the window capture-phase handler (enableListWheelScroll) which scrolls the textarea manually before TransformPane can react.
- Add maxHeight prop and container max-height for Lora Loader/Stacker/WanVideo nodes (modelType === 'loras'), matching canvas mode's height cap. Prompt/Text nodes remain uncapped.
