Feature summary: Create another page, add-work.html, similar to the ones created in T407385 and T407551, this time containing a basic form for creating a new work's item. The form should contain at least the fields "Title," "Description," and "Work type." However, unlike task T407551, the work type input field must implement autocomplete, searching Wikidata in real time for values of the P31 (instance of) property. For implementing autocomplete, you can try the item search endpoints of the Wikibase REST API: https://doc.wikimedia.org/Wikibase/master/js/rest-api/#/item%20search
Another way could be using the wbsearchentities action of the Mediawiki Action API: https://www.wikidata.org/w/api.php
If you discover a better approach, it's also valid. Please note that, whenever possible, we prefer to use the Wikibase REST API for interacting with Wikidata. While it's still under development and lacks several features, it's the most recent API, is undergoing significant development, and is likely more future-proof.
As with T407551, for now there's no need to add an action attribute to the form or make the form submission affect the Paulina website. This is a proof of concept. You just need to create the form and implement the real-time autocomplete for the "Type of work" input field.
Benefits: To make creating Wikidata items through Paulina user-friendly, it is important that the user does not have to enter the Wikidata QID of each statement's value, but can instead start typing the label, leaving Paulina the task of autocompleting and associating the label with a Wikidata QID, similar to what happens when adding or editing statements in Wikidata itself.
