The Crisp ownership check returned a generic internal error when the
managed plugin token was unset without logging server side, unlike the
sibling plugin-ID branch and every other internal path in the file. A
deployment with the token unconfigured but the provider somehow surfaced
would produce an undiagnosable error. Log the condition first, mirroring
the plugin-ID branch.
