fix(invitations): send the disclosure token for no-join previews too

A preview that predicted no join still tells the user nothing moves — the
empty disclosed set is now echoed on accept, so a join that becomes
possible between preview and accept (left another org, billing turned
usable, grants un-staled) conflicts with disclosure-outdated instead of
sweeping workspaces without a rendered notice.
