Shipment filter should make live database queries

[akircher]

• We have shipment table locally so queries should be fast
• Loading all shipments into memory on page load is a waste especially as number of shipments grows
• Some volunteers "wait" for their partner to add the shipment and then are surprised when it doesn't automatically appear in their shipment drawer. We have to instruct them to reload the page which is not ideal.
• What should appear in drawer with no search? No shipments (like drug search)? Or most recently added?

Deprioritizing since we won't have a lot of volunteers working on the same box
