feat: the menu suite (R1.1-R1.6, R1.10) and one shared log Konsole for every test run

Scripted menu input and Steamify's own status functions, journals free of duplicates,
--backend status as JSON, an older item shown as (update). The test scripts append to
$TEST_LOG and share one Konsole (common.sh view_start) instead of opening one each;
vmsuite.sh streams its output (sed -u). 36 checks pass.
