description: Fixed Angular 21 zoneless default causing async HTTP callbacks to not trigger change detection

Angular 21 defaults to zoneless execution. The project was missing zone.js entirely, so HTTP responses arrived but change detection never ran — components stayed stuck on loading states.

**Fix:** Added `import 'zone.js'` to [src/main.ts](src/main.ts) and installed zone.js as a dependency. This is the simpler fix over configuring provideZoneChangeDetection() manually.
