Unify order-list card into a single grid for consistent column alignment

One grid for the whole card (Bestellnummer/Datum spanning 2 of 4 tracks
from sm: up, everything else spanning 1) instead of two separate flex/grid
groups. Plain flex-wrap sized every field to its own content width, so a
field could start at a different x position from one order to the next
depending on how wide that particular badge label happened to be — a
grid's column tracks are fixed by the container width, identical on every
card regardless of content, which is what actually guarantees consistent
alignment across different orders.
