pama-imaging service returns 500 when called with meds

[dennispatterson]

In the future we may update the sandbox to add the ability to align services with specific tabs. In the meantime, the Rx View tab invokes the order-select hook and calls the pama-imaging service. Currently, this results in a 500 response from that service and an error logged to the sandbox's console as a result.

We should update the pama-imaging service such that if it receives draft orders that are not orders it cares about (e.g. this could be starting with checking if they're ServiceRequests), it returns an empty card array.
