On /overview Backups the card surface lived on .main, which wraps both the
body and the flipped footer — so the background overhung past the action
buttons. Move the card surface onto .backup-page-body (rounded bottom,
joined to the tab strip) and let the footer sit transparent below it,
matching the app Config tab's .tabs-content + .config-actions split.
