Use dropdown menu instead of button to edit the currency

[odin-h]

Problem

It's not apparent how you change the currency in the current edit container design. Also, using a button to open a new box requires more clicks.

Proposed solution

Make the currency label a dropdown instead of opening a new dialogue box to change the currency. Put a dropdown menu in place of the current text label of the selected currency on the right side of the price input.
