feat(lora-info): add Lora Info display node

Add a pure frontend node that shows filename and editable notes for
a selected LoRA. Connect any output from a LoRA Loader/Stacker/Randomizer/
WanVideoSelect to the lora_source input — selecting a LoRA in the source
widget updates the info display automatically.

- Python node (LoraInfoLM): display-only, no workflow execution
- Vue widget: filename label, auto-sizing notes textarea, save button
  with ComfyUI toast feedback on save
- Frontend extension: wire-based selection propagation with stale-response
  race guard; clears display on wire disconnect
- Backend: get-notes endpoint now returns file_path alongside notes;
  matching supports full-path lora syntax; fix NoneType crash in
  trigger words endpoint; document cache file_name invariant
- Wired into all four lora widget nodes (Loader, Stacker, Randomizer,
  WanVideoSelect)
