test: MMQA - 1907 - Refactor carousel.spec.ts to use POM and good practices

[LeVinhGithub]

Description

• Refactored test/e2e/tests/carousel/carousel.spec.ts to follow the Page Object Model by moving inline driver selectors and carousel logic into a new CarouselPage page object.
• Added test/e2e/page-objects/pages/home/carousel.ts with methods for loading the carousel, navigating slides, checking title/description, dismissing slides, and asserting visibility/dismissability.
• Replaced deprecated driver APIs in the carousel flow:
  • isElementPresent / isDescendantPresent → isElementPresentAndVisible for presence checks
  • manual absence assertions → assertElementNotPresent with guards for carousel/close-button checks
• Removed raw selectors, assert, tinyDelayMs, and this.skip() from the spec; tests now skip gracefully when no carousel is rendered.

Files changed:

• test/e2e/page-objects/pages/home/carousel.ts (new)
• test/e2e/tests/carousel/carousel.spec.ts

CHANGELOG entry: null

Fixes: MMQA-1907

Manual testing steps

1. Build the test extension:

yarn build:test

2. Run the carousel E2E spec:

yarn test:e2e:single test/e2e/tests/carousel/carousel.spec.ts --browser=chrome

3. Confirm both tests pass:

   • renders slides and each visible slide has title and description
   • dismisses slides that are dismissable and hides the carousel when none remain

4. Verify the spec no longer uses raw selectors or deprecated isElementPresent / isDescendantPresent calls.
