feat: Add LoRA selector modal to Cycler widget

- Add LoraListModal component with search and preview tooltip
- Make 'Next LoRA' name clickable to open selector modal
- Integrate PreviewTooltip with custom resolver for Vue widgets
- Disable selector when prompts are queued (consistent with pause button)
- Fix tooltip z-index to display above modal backdrop

Fixes issue: users couldn't easily identify which index corresponds
to specific LoRA in large lists
