Retain filename containment above 767px

At viewport widths of 768px or more, none of the new .account-status-card-* overflow rules apply, but this line removes ellipsis unconditionally. Because /admin-api/credentials accepts caller-supplied basename-only filenames without a length limit, a long unbroken filename can retain its intrinsic width on tablet or desktop and overflow the card or displace the Refresh button; keep truncation outside the mobile breakpoint or apply the min-width/wrapping constraints at every width.
