Add E2E coverage for dashboard widgets

[ekamran]

What?

Adds end-to-end test coverage for the AI dashboard widgets in wp-admin.

Why?

The dashboard widgets are a user-facing feature, but there was no browser-level test coverage for them. Adding E2E coverage helps catch regressions in widget visibility, onboarding state, and permissions.

How?

• Added a new E2E spec for the dashboard widgets.
• Verified that admins can see the AI Status and AI Capabilities widgets.
• Verified that the AI Capabilities widget shows the expected summary metrics and the provider capabilities section.
• Verified that the AI Status widget shows the getting started checklist when setup is incomplete.
• Verified that non-admin users do not see the widgets.

Use of AI Tools

I used AI assistance to help review the repository, draft the E2E test file, and iterate on the test assertions. I manually reviewed the implementation, validated the behavior locally, and verified the final test runs before submitting.

Testing Instructions

1. Start the test environment.
2. Run:
   npm run test:e2e -- tests/e2e/specs/admin/dashboard.spec.js
3. Confirm all 4 dashboard widget E2E tests pass.
4. Optionally verify manually in wp-admin that:
   • admins can see the AI Status and AI Capabilities widgets
   • the AI Status widget shows the onboarding checklist when setup is incomplete
   • non-admin users do not see the widgets

Testing Instructions for Keyboard

1. Open the WordPress admin dashboard.
2. Use keyboard navigation to move through the dashboard widgets.
3. Confirm the AI Status and AI Capabilities widgets are reachable and visible for admin users.
