Added an order details target

[js-goupil]

Resolves https://github.com/Shopify/pos-next-react-native/issues/37676

Background

This implements a new target for order-details actions. I also refactored some shared API code into an ActionTargetApi which will allow us to reduce code duplication a little bit. I also refactored some of the documentation.
