Class MJServiceWorkerModule

Bundles MJ Explorer's service worker concerns into one module:

• Conditionally registers @angular/service-worker based on enabled
• Exports UpdateNotificationComponent (standalone toast)
• Exposes UpdateNotificationService via providedIn: 'root'

Consumers should call MJServiceWorkerModule.forRoot({ enabled: ... }) exactly once in their root NgModule. Typically this is done internally by MJExplorerAppModule.forRoot(environment) so MJExplorer (and downstream Explorer-style apps) don't have to wire it themselves.

Pre-built ngsw-config.json ships at the package root; consumers point their angular.json serviceWorker field at: node_modules/@memberjunction/ng-explorer-service-worker/ngsw-config.json

If a consumer doesn't update angular.json (no SW worker built) AND doesn't flip enabled true in their environment, this module is a no-op. The app keeps working exactly as if the SW didn't exist.
