Added an Editor's Note action to the Power LoRA widget context menu

Hi, I updated the PR with the following changes:

- Added an `Editor's Note` action to the Power LoRA widget context menu so each LoRA entry can store a short note.
- Extended the widget state with a `note` field and merged incoming values with the default shape to keep older serialized data compatible.
- Centralized LoRA switching through `setLora()`, which now clears stale notes when the selected LoRA changes and resets cached LoRA info before refetching.
- Updated the canvas rendering so the note is displayed inline next to the selected LoRA name with truncation and lower visual emphasis.
- Synced the generated frontend output in `web/comfyui/power_lora_loader.js`.

In short, this update adds lightweight per-LoRA notes while keeping widget state backward-compatible and the generated web bundle in sync.

Please take another look at the Power LoRA Loader changes. The main functional addition is per-LoRA note support, and I also cleaned up the state hydration path so older widget payloads still load safely.
