Fix failing AppComponent unit test in v19 workspace

[rohansaini-02]

Context

While running the unit test suite (ng test), I noticed that the generated AppComponent spec fails to execute successfully.

Problem

The test suite expects the component to render a welcome header:

expect(compiled.querySelector('h1')?.textContent).toContain('Hello, helpline1097-ui-v19');

However, app.component.html has already been refactored to host the main <router-outlet></router-outlet>, causing the obsolete title assertion to fail.

Proposed Change

• Remove the obsolete title rendering assertion in app.component.spec.ts
• Ensure the spec suite verifies basic component instantiation and routing shell setup

Affected Areas

• File: v19/src/app/app.component.spec.ts

Deliverables / Checklist

• Update app.component.spec.ts assertions
• Verify unit tests pass successfully (npm run test)
