Adds the first browser-driven test to the project: PlaywrightTestBase starts
the app on a random port and drives a headless Chromium against it, and
FormViewPlaywrightTest covers the form's rendering, binder validation and the
save/reset buttons.
The tests skip themselves via a JUnit assumption when no browser can be
launched, so runners without Playwright browsers stay green.
