Rename the group-buying "Order lifecycle" cancel scenario to the exact name
the current order spec uses; a MODIFIED requirement replaces the whole block,
so the old name made archive refuse to drop the existing scenario.
Replace the placeholder Purpose in the archived address-book spec, which the
wave-7 archive left as TBD and strict validation rejected.
openspec validate --all --strict is green again.
