refactor: duplicate member details tab for parallel service history & accumulator

Instead of navigating back and forth, step4 opens the member details URL
in a new tab. Tab A clicks service history and CDP-prints the history PDF.
Tab B clicks View Accumulator and CDP-prints the accumulator PDF (waits
up to 15s for vm.hasResults, then captures whatever is on screen).
Eliminates the Chrome freeze from back-navigation and the empty-accumulator
race condition.
