Once offload is configured on a mapping row, there is no way to clear or remove it. The only workaround is deleting the entire row and recreating it.

MTV 2.11.0

Always 

1. Open a storage map that has offload configured (or configure it via the edit modal)
2. Click Edit on the Map section to open the edit modal
3. Expand "Offload options (optional)" on the row with offload
4. Try to clear the Offload plugin dropdown (click it, then click the selected option)
5. Observe the dropdown closes but the value remains selected

The offload plugin stays selected. There is no way to deselect it or
remove the offload configuration without deleting the entire mapping row.

Provide a way to remove offload from a mapping row, such as:
- A "Clear" or "None" option in the offload plugin dropdown, or
- A "Remove offload" button inside the expandable section
