`MrmWarehouseScrapComponent` is an Angular dashboard widget for loading, preparing, and displaying warehouse scrap data. It checks authorization, responds to lifecycle changes, calculates monthly totals, formats month and price values, and saves dashboard state.

## Usage

```ts
import { ComponentRef } from '@angular/core';
import { MrmWarehouseScrapComponent } from './mrm-warehouse-scrap.component';

function refreshWarehouseScrapWidget(
  componentRef: ComponentRef<MrmWarehouseScrapComponent>
): void {
  const widget = componentRef.instance;

  // Angular runs ngOnInit during initial change detection.
  componentRef.changeDetectorRef.detectChanges();

  // Reload data after an external dashboard filter or refresh action.
  widget.getDashboardData();

  const monthLabel = widget.translateMonthName();
  const formattedPrice = widget.getpriceFormatted();

  console.log({ monthLabel, formattedPrice });
}
```

## AI Coding Instructions

- Let Angular invoke `ngOnInit`, `ngOnChanges`, and `ngOnDestroy`; do not call lifecycle hooks from application code.
- Call `GetAuthorizationAccess()` before exposing or loading dashboard scrap data.
- Keep data preparation in `initalizingData()` and monthly aggregation in `calculateSumByMonth()` rather than duplicating calculations in templates.
- Preserve the existing `initalizingData` method spelling when calling or modifying it.
- Use `saveDashboardData()` for dashboard-state persistence and `getDashboardData()` when widget data must be refreshed.
