Hub section toggles do not hide matching nav tabs
**Severity:** Medium
**Area:** Project hub / settings
Admin "Public hub" toggles (`hub_show_feedback`, etc.) only change content on `/{projectSlug}`. Primary tabs (Feedback, Roadmap, Updates, Docs) always show regardless of toggles.
Admins can hide a section on the hub while navigation still advertises it, which feels broken.
**Fix:** Either gate `ProjectTabs` on the same hub flags or document that toggles are hub-only and rename the settings copy.
