Automated functional testing for Autocomplete Deluxe (2.1.x)

Problem/Motivation

Autocomplete Deluxe has no automated functional testing, so every change is checked by hand. The widget is JavaScript heavy, which is exactly the kind of code that quietly breaks: the delimiter, the Backspace key, the suggestion list, the new term message and the save flow all live in the browser.

Steps to reproduce

1. Change anything in the widget JavaScript.
2. Nothing tells you which of the widget behaviours stopped working.

Proposed resolution

Add the same automated functional testing the sibling modules use: webship-js, which drives Playwright through Cucumber features, with a hidden test recipe that provisions the content type, the vocabulary and the field so the suite does not depend on what the install profile ships.

Twenty one scenarios: login, the taxonomy set up, the widget render, the stylesheet each admin theme gets, the suggestion list, multiple values, new terms disabled, the keyboard and the minimum length, the save flow, the help page, accessibility and a mobile breakpoint.
