feat(radar): fill radar in split-screen via measured window size

The previous compact-mode trigger used currentWindowAdaptiveInfo(),
which reports the full-screen size class in split-screen / multi-window,
so the radar never enlarged there. Measure the actual window bounds with
BoxWithConstraints: compact (radar weight 1f fills all space, pager fixed
132dp strip) when maxWidth < 600dp && maxHeight < 480dp.

build: release version 4.4.7-ba7opf.17.6 (529)
