         Updates the sale order lines based on the selected partner.

         This method is triggered when the `partner_id` field changes. If a partner is selected,
         it searches for all sale order lines associated with the partner's completed or confirmed
         sale orders ('sale' or 'done' states). It then creates new lines based on the retrieved
         sale orders and updates the `order_details_ids` field with these new lines.

         If no partner is selected, it clears the `order_details_ids` field.

         Fields Updated:
         - order_details_ids: A list of order lines (product, quantity, unit price, tax, and subtotal)
                              associated with the partner's completed or confirmed orders.

         Behavior:
         - Adds new order lines when a partner is selected.
         - Clears the order details if no partner is selected.
