IgbGrid: NotifyInsertItem and NotifyRemoveItem no longer re-render

[TomoyaWashio]

Description

After upgrading Ignite UI for Blazor from 25.1.82 to 25.2.83, the Notify-based methods of IgbGrid (NotifyInsertItem and NotifyRemoveItem) no longer re-render the grid.
The underlying data source is modified correctly, but the change is not reflected on screen. The same code worked as expected in 25.1.82.

Steps to Reproduce

1. Create an IgbGrid bound to a List via Data, with @ref set and a PrimaryKey defined.
2. Add an item to the bound list in code-behind, then call grid.NotifyInsertItem(list, index, newItem).
3. Observe the grid — the new row is not rendered.
4. Remove an item from the same bound list in code-behind, then call grid.NotifyRemoveItem(list, index, removedItem).
5. Observe the grid — the removed row is still displayed.

Actual Result

The item is added / removed to the data source, but the grid is not re-rendered and the new row does not appear on screen.

Expected Result

Calling NotifyInsertItem / NotifyRemoveItem should re-render the grid and display the newly added row, as it did in 25.1.82.
