CLC-2548 Update grossly out of date my/status JSON contracts

https://jira.ets.berkeley.edu/jira/browse/CLC-2548 will involve moving some data structures out of the "my/status" API feed and into another.

However, we've done a very poor job of keeping the API contracts for "my/status" updated to reflect reality. This PR makes the dummy JSONs match our current implementation so that later refactoring will be easier to understand and test.
