Select a delivery time slot

Submits the chosen delivery time window (lower and upper datetime bounds). The slot is validated to ensure it is still available. On success, the shipping option and shipping amount are calculated and stored in the pre-order, and the delivery range is recorded.

Required Fields:

• lower: Start of the delivery time window (ISO 8601 datetime with timezone).

• upper: End of the delivery time window (ISO 8601 datetime with timezone).

Validation:

• The submitted range must still be available according to SlotService.is_delivery_range_available().

State Update:

• pre_order.shipping_option is set to the first available shipping option.

• pre_order.shipping_amount is calculated.

• pre_order.data['delivery_range'] is set to the selected range.

• If DELIVERY_BAGS_CONF.auto_run is enabled, DeliveryBagsPage is auto-processed.

• For retail store delivery options, the shipping address is replaced with the retail store address.

Backward Navigation:

• When navigating backward, delivery_range is reset, shipping_option is cleared, and shipping_amount is set to 0.00.
