fix: compact print layout for the order blank and receipt

.sun-doc-grid (client/phone/date/address) fell back to whatever the
last matching max-width media query set, and print rendering commonly
evaluates those against the page's content width - narrow enough to
trip the existing max-width:700px breakpoint and stack every field
onto its own line instead of the intended 2-column grid. Combined with
generous screen-sized padding/font-sizes carried into print, a normal
order routinely spilled onto a second page.

Adds an explicit @media print block that puts client/phone/date/address
in a single row regardless of viewport width (grid-auto-flow:column),
sets an explicit @page size/margin instead of relying on the browser
default, and shrinks fonts/padding throughout (header, field grid,
table rows, summary, footer) for both the order blank (.sun-doc) and
the receipt (.sun-receipt, which reuses the same grid). Verified with a
standalone reproduction of the markup/CSS - a 2-line order now renders
as one compact page instead of stacking every field before ever
reaching the table.
