feat(FN-3077): enforce plugin AI security scan gate across install flows

- Add core plugin AI security scan module and schema support for scan toggle/state metadata
- Enforce scan checks during CLI and dashboard plugin install flows, with preserved API error status on scan failures
- Expose plugin scan toggle and rescan actions in dashboard/plugin manager with route and UI coverage
- Update plugin authoring and CLI/dashboard docs, plus add changeset for published CLI package
