Reverts the earlier Apache-2.0 change in favour of a proprietary licence
matching the other internal ATT plugins (att-consent). Grants use only to
authorised sites; all other rights reserved. MIT carve-out preserved for
vendored PUC.
Internal-only tool, so no distribution obligations under either license.
Apache-2.0 chosen for its explicit patent grant. Can be relicensed to GPL
later if wp.org distribution becomes relevant.
