dev/mock-api.mjs answers the endpoints the screens call, with surrogate data, and keeps
what is changed in memory (zones, scopes, users, groups, rules, sessions, the cache).
`npm run mock` starts it on 127.0.0.1:5380, where the dev server's proxy already points.
.claude/launch.json starts the mock and the console together in the preview pane.
