docs(templates): fix groff Build: lines to match check-templates

ordo.ms's own Build: comment omitted -P-pa5 entirely, so the documented
command produced A5-sized content on a physical A4 PDF page
(595x842pt instead of 419x595pt) -- verified by running the command
verbatim and reading pdfinfo. Both .ms Build: lines were also missing
-Kutf8 and -t, which the Makefile's check-templates target already
carries: without -Kutf8, accented Latin names (e.g. Peñafort) render
as mojibake, confirmed by extracting text from the rendered PDF.

Bring both templates/ef/ordo.ms and templates/ef/grid.ms in line with
the Makefile's actual invocation (-ms -t -Tpdf -Kutf8 <papersize>), so
a user copying the Build: line gets the same result as
'make check-templates'. Updated the two golden fixtures that pin these
templates' rendered output byte-for-byte to match.

Verified every documented build command (README's two pdflatex
invocations, both .ms lines, both .typ lines) by running it verbatim
and checking pdfinfo/pdftotext output; no other flavour's Build: line
or man page example was affected.
