pet.trezy.getResetStatus

The caller's most recent account reset, if they have ever started one. Answers the question the client asks on every load: is a reset running, did the last one finish, and did it finish cleanly. A QUERY rather than a procedure because it is read-only and polled while a reset runs. It takes no parameters at all — it reports on `caller_did` and nothing else, so there is no way to watch somebody else's reset. Anonymous callers get a refusal rather than a 401: a Lua script cannot set its own HTTP status, and this is a status read rather than an action, so a 200 carrying `not-authenticated` is the honest shape.
