feat: add loadWorkflow and setSetting actions to QA recorder

- Add loadWorkflow action to load workflow JSON from URL
- Add setSetting action to configure ComfyUI settings
- Improve reproduce mode prompt to emphasize establishing prerequisites
  (save workflow first, make it dirty, add needed nodes, etc.)
