/**
* @description
* A component that disables content and displays a semi-transparent overlay with optional notification.
* Manages focus state and provides visual feedback when content is temporarily unavailable.
* Useful for indicating loading states, processing operations, or temporarily disabled sections.
*
* @usageNotes
* ### Basic Usage
* ```html
*
*
*
* ```
*
* ### With Notification
* ```html
*
*
*
*
*
* ```
*
* ### Conditional Disabling
* ```typescript
* // Component
* isFormDisabled = false;
*
* submitForm(): void {
* this.isFormDisabled = true;
* this.api.submit().subscribe(() => {
* this.isFormDisabled = false;
* });
* }
*
* // Template
*
*
*
* ```
*
* ### Accessibility
* - Automatically sets `aria-disabled="true"` on focused elements when disabled
* - Manages focus state by storing and restoring last active element
* - Sets `tabindex="-1"` on disabled elements to prevent keyboard navigation
* - Displays growl notification when clicking disabled content (if `disabledText` provided)
* - Restores focus to previously active element when re-enabled
*
* ### Notes
* - Wraps content with `` for flexible composition
* - Requires `EuiGrowlService` for notification functionality
* - CSS class `eui-disable-content--disabled` applied when active
* - Does not prevent programmatic interaction, only visual and focus management
* - Use for temporary disabling; for permanent states, use native `disabled` attribute
