feat: add member details PDF step to MH history and CMSP flows

After clicking the member ID link, print the member details page via CDP
before navigating to service history. Adds member details as a panel in
the side-by-side PDF viewer: MH History shows 3 panels (eligibility,
member details, service history); CMSP shows 4 panels (eligibility,
member details, service history, accumulator).
