Disallow editing Fulfillment preference when Request is in Open - Awaiting delivery or Open - Awaiting pickup

Purpose: To disallow editing of fulfillment preference when Request is in Open - Awaiting deliver or pickup. Editing at this point would be complicated to handle and is probably not a priority. Can add this capability later, if prioritized.

Scenarios:

1. Scenarios
   • Given a request is in Open - Awaiting delivery or Open - Awaiting pickup
   • When displayed in edit mode
   • Then the Fulfillment preference menu should be uneditable
