launch_live.ps1: enlarge exploded cockpit windows +25% (0.75 scale)

Per user request, bumped the cockpit MFD/radar windows from 0.6 to 0.75 of
native 640x480 (MFD 384->480, radar 288->360 logical). Live-verified on the
secondary: MFDs now render 331x266 (was 267x218, ~+24% after the primary's DPI
downscale), radar 251x346, all six still fit the 1707x1067 secondary with
margin, renderer unchanged on the primary. No wire stall.
