Fill in some straightforward Maniphest transactions for `transaction.search`

Summary:
See PHI197. Populates "status" transactions and a few other obvious types where there's no security/performance/payload/formatting issue I can come up with.

The names here are the same as the names for editing with `maniphest.edit`.

Test Plan: Used `transaction.search` to retrieve transactions of all new types.
