fix(dashboard): align droid config diagnostics with factory paths

- replace ~/.config/factory/config.json diagnostics with legacy ~/.factory/config.json

- keep ~/.factory/settings.json as the primary BYOK source in UI + API payload

- update droid dashboard tests and frontend typings for legacyConfig
