As a member of the fundraising team,
I want to find specific donations and their metadata in the Fundraising Operations Center,
so that I can support the donors during the campaign
- Donation list shows SUB donations as well as all other payment types as before (adapt to changes done to store in T167886)
- Donation detail lightbox shows transaction confirmation date (see T167882)
- Donation list is filterable by SUB payment type
Part of this story is to develop tests for this part of the application and to refactor this part to make it more testable. The end result doesn't need to be a Silex-based controller with a fully-fledged end-to-end test and unit test suite, but more of "Enough tests to prove that the new functionality doesn't break anything".
