Make PonderQuestionEditor use ApplicationTransactions
Summary:
Ref T3373. Make PonderQuestions editable and use transactions.
This temporarily disables some stuff:
- email;
- feed;
- comments;
- voting.
I'll restore those in followups and wait to land this until they're at least mostly back online.
The transactions themselves also need more string/color/icon work.
Test Plan: Created and edited questions. Viewed transactions.
