fix: remove label cut lines and zero-pad printed dates

The dashed rectangle drawn around every label slot (a cut/crop line)
wasn't needed and is gone, along with the width/height params that
existed only to draw it. Dates on the label (bottling date, MHD) now
use { day: '2-digit', month: '2-digit' } so single-digit values print
with a leading zero (05.03.2026, not 5.3.2026) - the default 'numeric'
formatting was dropping it.
