Add full text search to maniphest.query

Summary: ...also swapped "status" and "order" so "status" is first, as in my testing it was sub-optimal to specifiy status (more of "what i want") after order ("how I want it")

Test Plan: ran various queries on my test instance via conduit console and the results all seem correct
