Separate handle "status" and "availability"
Summary: Ref T7707. Handles currently have a "status" field and a "disabled" field. The "status" field has these possible values: "open", "closed", "1", "2". durp durp durp Instead, do: - status = <open, closed> - availability = <full, partial, none, disabled> I think these make more sense? And are a bit more general? And use the same kind of constants for all values! Test Plan: Looked at all affected handles in all states (probably).
