Allocations - Draft Order - What to do?

As a store manager I want any draft orders that I have in place when an allocation is ended to account for that change so that I can place an order for an appropriate quantity

Notes
There are two scenarios that I can think of:

1. Allocation Ended - Draft Order created with allocation, allocation ended
   • An order is created, which contains an item that is on allocation
   • The order is saved as draft
   • The allocation is ended
   • The order is submitted
     • In this instance, there is no need to restrict the quantity that the user can order, based on the previously ended allocation
   • Note - this affect all draft orders when ANY existing allocation is ended. When an allocation ends, there isn't a concept of "this is going to be replaced by another allocation" - the system has no way of knowing if the allocation is going to be replaced or not.
2. Allocation Updated - Draft Order created with allocation, allocation ended, new allocation imported delivery date of draft order falls within new allocation period
   • An order is created, which contains an item that is on allocation
   • The order is saved as draft
   • The allocation is ended
   • A new allocation, for the same item is added, and the allocation period spans the delivery date of the draft order
   • The order is submitted
     • In this instance, the validation should be rerun, on order submission, to take into account the new allocation
   • Note - this will also affect draft orders when ANY new allocation is imported. When an allocation is created, there isn't a concept of "this is replacing an old allocation" - it's always just a brand new allocation.

Acceptance Criteria

1. Confirm when an allocation is ended, that was used by a draft order, that the order can be successfully Placed without any allocation restrictions on the quantity ordered
2. Confirm when an allocation is ended, that was used by a draft order, and a new allocation is created for the same item spanning the delivery date, that allocation validation is performed (using the new allocation) when the order is placed
