fix: Make Drupal Website Dashboard compatible with Display Builder 1.0.0-beta9 and later

Problem/Motivation

Display Builder 1.0.0-beta9 (22 October 2026) makes every buildable implement AccessibleInterface::access(), and an override buildable getDefaultSources() and deleteOverride() in place of revert(). 1.0.0-beta10 (6 November 2026) also drops the static instance ID helpers and makes getPrefix() an instance method. Web Dashboard 1.0.6 has none of this, so any site that resolves beta9 or later stops with a PHP fatal error while installing.

Steps to reproduce

1. Require drupal/webdashboard:1.0.6 with drupal/display_builder:1.0.0-beta9 or later.
2. Install the module, or a recipe or profile that installs it.

PHP Fatal error: Class Drupal\webdashboard\Plugin\display_builder\Buildable\DashboardBuildable contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (Drupal\Core\Access\AccessibleInterface::access)

Proposed resolution

• Both buildables implement access(), as the page layout buildable does, in place of the static checkAccess().
• The personalized dashboard implements getDefaultSources() and deleteOverride(), and the reset form calls deleteOverride().
• Add toUrl() for beta10, and keep the helpers beta9 still asks for. The prefix becomes a class constant, so the same code runs on beta9 and beta10.
• composer.json requires drupal/display_builder:^1.0.0-beta9. Beta8 no longer works.
