As a store employee, I want to be able to switch between modifying all items or just one item, so that I can efficiently update product information as needed.

Description Currently, employees must modify each item individually. Adding a toggle button will allow the employees to choose between:

1- Modifying a single item (for detailed adjustments). 2- Modifying all items at once (for bulk updates like discounts or availability).

This will improve workflow efficiency and reduce repetitive manual updates.

Acceptance Criteria

• A toggle button must be available on the dashboard.
• Default state: The toggle should start in "Single Item" mode.
• When "Modify All" is selected, changes apply to all items at once.
• When "Modify One" is selected, changes apply to only the selected item.
• The toggle should visually indicate the selected mode.
