fix(gui): stop an open folder clipping its own uninstall badges

The folder's grid scrolls, so it clips anything outside its padding box
— and reorder mode's uninstall badge deliberately overhangs the top-left
corner of every tile. The top row's badges therefore rendered as flat
tabs rather than circles, on the one surface where they are a touch
user's only way to uninstall an app they have filed away.

Give the scroller 9px of top padding for the overhang to sit in and take
it straight back off as margin, so the card and everything in it stays
exactly where it was.
