fix(widgets): reuse orphaned DOM containers after undo/redo in Vue render mode

In ComfyUI Vue render mode, WidgetDOM.vue reuses its component instance
during undo/redo without re-calling mountWidgetElement(), leaving newly
created widget containers detached from the DOM.

- AutocompleteTextWidget: scan for empty containers by ID prefix and reuse
- Loras widget: scan for empty .lm-loras-container elements and reuse
- Prevent duplicate event listeners by guarding listener setup on new
  containers only
- Keep container in DOM on cleanup (clearChildren instead of remove)
  so it can be found and reused by the next factory invocation
