feat: Build the default dashboards with Display Builder on Web Dashboard

Problem/Motivation

The Web Dashboard recipe currently ships no default dashboards. The Drupal CMS Dashboard module requires Layout Builder, which this recipe does not want to depend on.

Steps to reproduce

Install the webdash recipe on a fresh website_starter site and look for the Webmaster and Editorial dashboards.

Proposed resolution

Rebuild the Webmaster (-20) and Editorial (-10) default dashboards as webdashboard config entities built with Display Builder instead of the Dashboard module/Layout Builder. Add views.view.webdash_drafts. The recipe installs display_builder, webdashboard and webdashboard_views, and composer requires drupal/core ~12, display_builder and drupal/webdashboard ~12.0@dev.

Depends on webdashboard MR !1 (issue #3622694).

Tested on a fresh website_starter install: layout_builder/navigation/dashboard not installed, admin sees both dashboards, content editor only sees Editorial, no log errors.
