Migrate FaceBookLoginTest to Playwright TypeScript

[devin-ai-integration]

Summary

Ports the single legacy Selenium/TestNG class FaceBookLoginTest (plus its page object) to a self-contained Playwright TypeScript project under e2e-playwright/ (own package.json, playwright.config.ts, chromium-only). No Java sources, pom.xml, or TestNG suites are touched — the legacy suite still runs and still fails as designed.

Locator change that matters: the legacy page object used @FindBy(id = "email"), but current facebook.com renders generated ids (id="_R_1h6kqsqppb6amH1_"), so the fields are addressed by their stable name attributes:

emailInput    = page.locator('input[name="email"]');
passwordInput = page.locator('input[name="pass"]');

Honest handling of the legacy assertion: the Java test ends in Assert.assertTrue(false, "Login failed : Test failed") — an unconditional failure, not a statement about the app, and there are no credentials in the repo to actually authenticate with. Rather than rewriting it into something that passes vacuously, the spec splits the intent:

test('loads the login page and submits the credentials entered', ...)   // steps 1-2, real assertions
test.fixme('reports a successful login - legacy assertion is an unconditional failure', ...) // step 3, pending with explanation

The passing test asserts only what it can honestly observe: the login form is visible, both fields hold the values entered ("abc"/"abc", as in the legacy test), and after submit the browser is still on a facebook.com host. Local run: 1 passed, 1 skipped (the fixme).

CI: .github/workflows/playwright-facebook.yml runs npx playwright test tests/facebook-login.spec.ts on pull_request (paths-filtered to e2e-playwright/** and the workflow itself) and uploads the HTML report. Note the spec hits the live facebook.com, so it depends on that being reachable from the runner.
