Remove NotificationRepositoryFactory, NotificationServicesFactory, and
NotificationRepositoryInterface — all single-consumer abstractions with
no polymorphism benefit. Simplify container registrar to wire services
directly. Extract shared listener logic (sanitizeTenantIds,
resolveDisplayName, resolveUuid) into NotificationListenerTrait,
eliminating duplication across 4 listeners.

NotificationsAuthorizationPolicy was never registered in the container,
so ModuleClassResolver could not instantiate it (requires PermissionService).
This silently prevented the notifications.view permission from being granted,
hiding the bell icon in the topbar.

In-app notification system with topbar bell icon, dropdown panel,
mark-as-read/dismiss actions, and scheduled cleanup of old read
notifications. Includes event listeners for user.created and
user.deleted events, authorization policy, and full test coverage.
