fix: wait for accumulator data before CDP print in CMSP flow

step7 now waits for button[ng-click='vm.printResults()'][ng-if='vm.hasResults']
to become visible before printing — that element only renders once Angular
has loaded the accumulator data, so the CDP capture is no longer racing
against the async data fetch.
