Closes #16

Adds the first browser-driven test to the project, using the FormView as the example the issue asked for.

What's in it

e2e/PlaywrightTestBase — @SpringBootTest(webEnvironment = RANDOM_PORT) starts the app, Playwright launches a headless Chromium against it. One fresh BrowserContext per test, so each test also gets a fresh Vaadin session. Provides navigate("<route>") and the page.
e2e/FormViewPlaywrightTest — 5 tests:
- form renders its fields, Age is prefilled with 37 and read-only
- saving with empty required fields shows the error notification
- saving with an invalid email shows the error notification
- saving valid input shows Saved: Max Mustermann
- reset clears the entered values

Notes

Assertions match the English captions. German is the unsuffixed fallback bundle (translations.properties), so de is not a provided locale and Vaadin serves translations_en.properties even for a German browser. The base class pins the context locale to en-US to make that explicit rather than implicit.
Skips instead of failing when no browser is available. Playwright downloads its browsers into ~/.cache/ms-playwright on first use; if that is not possible (offline runner, missing system libs), the tests abort via a JUnit assumption so CI stays green rather than going red on infrastructure.
CLAUDE.md updated: the "no test sources exist yet" note was already stale (GridStackViewTest exists), and the autofix rules' <dein Testkommando> placeholder is now ./mvnw test.

CI / build-and-test (pull_request) Successful in 2m16s

Details

a996269aff

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.

Closes #16
