Add a meaningful automated functional test suite for the Hero Slider content type

Problem/Motivation

The Varbase Hero Slider 1.1.x tests/features/drupal/** webship-js suite is too thin: the scenarios only assert that pages are reachable (for example "I should not see Page not found"). That is not a meaningful functional test — it verifies neither the provided behaviour nor the real, labelled fields of the Hero Slider content type.

Since the recipe redesign (#3609140) the module's recipes/default installs a complete Hero Slider content type (node type varbase_heroslider; fields field_brief, field_link, field_media_single; the varbase_heroslider entity queue; the varbase_heroslider view; and editorial permissions granted to the editor, content_admin and site_admin roles). None of that behaviour is actually exercised by the tests.

Proposed resolution

Replace the thin reachability scenarios with a meaningful webship-js (Playwright + Cucumber-js) BDD suite that asserts visible labels, roles and the real provided behaviour of the Hero Slider content type:

• The Hero Slider add form exposes its real labelled fields (Slide title, Slide text, Call for action link, Slide media (image/video)).
• An editor creates a Hero Slider slide end to end — title, brief, call-to-action link and an uploaded media image — and the saved node renders the entered title, brief text and its media image.
• The varbase_heroslider entity queue exists ("Hero Slider") and a created slide can be pushed to it and is then listed in the subqueue.
• Access control: an editor can reach the Hero Slider add form; an anonymous visitor is denied (asserting the visible access outcome, not reachability).

Add the supporting custom step definitions (media-library upload, publish-aware save, entity-queue widget, media-render and access-denied assertions), a small test image fixture, and wire the CI webship-js-test job to create the Editor test account and run the suite. All CI jobs remain blocking (allow_failure: false).
