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.
