improve(control-ui): move dev branch badge to its own footer strip (#104300)

The sidebar footer icon row got crowded with the inline branch label.
The dev-checkout branch now renders on a slim tinted strip above the
icon bar with a git-branch icon, keeping the full name readable and
the footer controls uncluttered.
