feat: Move Trello card to Packing when inspection is passed

- Create InspectionPassed event
- Create MoveCardToPackingOnInspectionPassed listener
- Register event listener in EventServiceProvider
- Dispatch event when markInspectionPassed() is called

Now when an order passes inspection on the ops page, the Trello card
automatically moves from Inspection to Packing list.
