fix: hide sidebar nav until plugins enabled, route to first active plugin

- Hide Dashboard link and sidebar nav items when no plugins are enabled
- OverviewPage (/) now redirects to the first enabled plugin page instead
  of always going to /dashboards/dashboard
- When no plugins are enabled, redirect to /settings/plugins
- Add hasAnyEnabledIntegration() and integrationPath() helpers
