Implement search functionality for payments

[dotmacro]

Problem

On testing and live, the "Completed" tab on the "Payments" view shows a search box and a loupe icon. The user can type text into the search box, but there is no way to submit the query -- neither clicking the icon nor hitting the enter key does anything. Search is not implemented.

Solution

Implement this search function. (In the meantime, hide the non-functional search box and loope from the UI.)

I just investigated this issue and it looks like the search function is implemented but currently broken due to this run-time error.

FYI, the search is executed for each keystroke not by any call-to-action.
