Add reset button if needed to each layout variant

The issue is that EntityDataTable stores column widths and column order in local state. This is intentional: it keeps column resizing and reordering responsive and avoids UI freezes while the user interacts with the table.

However, when a layout reset is triggered, the persisted layout preferences are reset, but the local column state inside EntityDataTable is not reset at the same time. As a result, the UI can continue showing the previous column order or widths until the table is remounted or reloaded.

This is especially tricky for resets triggered from the top section, because the top section is rendered inside PaginatedEntityTable, while the column state lives deeper inside EntityDataTable. The top section currently has no direct access to that local state, so we need a way to notify EntityDataTable that a layout reset happened and that it should also reset its local column order and width state.

For now, I just removed reset functionality from the top section items, as we can do that from the reset all columns button.
