Order Assignment Routing

[DakotaCondos]

As the Order Service,
I want to submit order assignment events for specific bots,
so that the simulator can route each order to the selected bot object for validation and delivery processing.

Acceptance Criteria

• Given the Order Service has selected a bot for an order
  When it publishes an order assignment event
  Then the event includes bot ID, order ID, requested items, and GPS destination.

• Given the simulator receives an order assignment event
  When the specified bot exists
  Then the simulator routes the order assignment to that bot object.

• Given the simulator receives an order assignment event
  When the specified bot does not exist
  Then the simulator publishes a BotNotFound order response event.

• Given a bot object receives an order assignment
  When the bot determines whether it has enough available, unreserved stock to fulfill the order
  Then the bot validates the order and returns the appropriate order response.

• Given the bot returns an order response
  When the simulator receives that response
  Then the simulator routes the response back through Event Hub for the Order Service and other consumers.
