Implements a dedicated page for viewing detailed stock picking information.
- Introduces `getStockPikingById` API call to fetch a single stock picking record by ID.
- Enhances `MainAppbarComponent` to support customizable leading widgets, enabling a back button on detail pages.
- Improves `QuickActionComponent` by allowing optional `onTap` callbacks for actions, making buttons conditionally visible and reusable across different contexts.
- Adds `margin` property to `StockPickingCard` for flexible layout adjustments.
- Refactors `ReceptionDetailsPage` to utilize the new API call and display a single stock picking's details, adapting its app bar and quick actions accordingly.
Refactors the "Quick Actions" section on the reception page into a new `QuickActionComponent`.
This improves modularity and reusability of the quick action UI pattern. Also adjusts vertical padding on the main page content for a cleaner layout.
