Guest checkout orders viewing

As an guest customer I would like to find and view my orders on the website.

Use cases:
Customer may want to check order status straight after purchase (email may not yet arrive)
Customer lost/deleted email with order details

TD:
Separate search page with exact matches on order number customer first, last name and email. (Need to be strict, so not to expose the details)
Only guest orders (CustomerOrder.customer == null) should be shown
Shop must have a setting to allow "Find orders" page
Uri: /orderstatus
REST API must be accounted for
