[TASK] Use "new record wizard" to render dashboard widgets

In order to streamline the backend UI and to re-use introduced web
components, the "Add widget" wizard in the dashboard module now utilizes
the `@typo3/backend/new-record-wizard` module that is already known from
the Content Element creation wizard.

As a small quality-of-life change, the modal title now includes the name
of the dashboard as well.
