User Story 32, Admin can see all orders

[memcmahon]

As an admin user
When I log into my dashboard, "/admin/dashboard"
Then I see all orders in the system.
For each order I see the following information:

- user who placed the order, which links to admin view of user profile
- order id
- date the order was created

Orders are sorted by "status" in this order:

- packaged
- pending
- shipped
- cancelled

DO THESE STORIES FIRST:

• User Story 56, Admin User Profile Page

Checklist:

• base tests are written
• base code is written to pass tests
• edge case ("sad path") tests written (if required)
• edge case code written (if required)
• code is reviewed
• branch is merged
• all tests still pass
