/**
 * Read-only company-context Active Modules index.
 *
 * Lists every module the super admin has activated on this instance
 * (Module::enabled = true) and reports whether each one has registered a
 * settings schema. The frontend uses this to render the company-context
 * "Modules" landing page with a Settings button per active module.
 *
 * Activation is instance-global; per-company customization happens through
 * settings (per CompanySetting under the module.{slug}.* prefix).
 *
 * Slug convention: nwidart stores the module's PascalCase class name in
 * `modules.name` (e.g. "HelloWorld"), but URLs and registry keys use the
 * kebab-case form ("hello-world") for readability. We normalize via
 * Str::kebab() so module authors can call Registry::registerMenu('hello-world')
 * naturally without thinking about the storage format.
