### Description

Expandable drawer component that slides out from the sidebar to display additional content or details. Provides a secondary panel for contextual information, settings, or extended navigation without leaving the current view. Manages expanded/collapsed state with corresponding CSS classes for animation and positioning. Prevents event propagation from drawer content to avoid unintended sidebar interactions.

Example :

    <!-- Sidebar drawer for user profile details -->
    <eui-app>
      <eui-app-sidebar>
        <eui-app-sidebar-header>
          <eui-app-sidebar-header-user-profile
            (toggle)="onSidebarProfileToggle($event)"
            [hasProfileDrawer]="true">
          </eui-app-sidebar-header-user-profile>
        </eui-app-sidebar-header>

        <eui-app-sidebar-drawer [isExpanded]="drawerExpanded">
          <p><strong>User Profile Details</strong></p>
          <p>Additional user information and settings</p>
        </eui-app-sidebar-drawer>

        <eui-app-sidebar-body>
          <eui-app-sidebar-menu [items]="sidebarItems"></eui-app-sidebar-menu>
        </eui-app-sidebar-body>
      </eui-app-sidebar>
    </eui-app>

Example :

    drawerExpanded = false;

    onSidebarProfileToggle(event: any): void {
      this.drawerExpanded = !this.drawerExpanded;
    }
