feat(templates): the ordo booklet flows continuously, not one week per page

One week per page filled roughly the top third of every A5 page and
cost 65 pages for a year that needed far fewer -- the original
requirement, reversed here: a full 7-day week already occupies most
of an A5 page even at reduced type, so the real saving was always in
the year's many SHORT boundary weeks (a month's first/last week is
rarely a full seven days), not in packing two full weeks together.

lib/render/view.ml gains a [first] field on every week object (true
on a month's own first week, the same 'cheap flag beats invented
template logic' call [last] already made for grid rows) -- there is
still no {{../}} parent-path syntax for a template to test this any
other way.

ordo.tex: the per-week \clearpage is gone. Every week keeps its
existing small header line; the month's own first week additionally
prints a large, ruled banner. \needspace (a template-local LaTeX
dependency, not one of the frozen OCaml deps) keeps a header from
being stranded alone at a page's bottom -- and a real, separate bug
surfaced building it: \label placed BEFORE \needspace captured the
OLD page number when \needspace went on to force a break, producing
a step-stale \pageref in the TOC (fixed by moving \label after both
needspace checks). The day box itself is tightened (rank/colour
folded onto the same line as the citations -- an A5 box is far wider
than tall, so this fits even Holy Week's longest citations with room
to spare) so a second week routinely shares a page with the first.
Measured result: 65 -> 53 pages, two pdflatex passes still settle the
TOC, zero orphaned headers, zero overfull boxes.

ordo.typ: the per-week #pagebreak is gone; #show heading's own
block gains sticky:true, Typst's built-in answer to what ordo.tex
needs \needspace for. The month banner needed its OWN sticky:true,
found live: without it a banner could sit alone at a page's bottom
with the entire month pushed to the next page -- not caught by a
check for an orphaned HEADING, since the banner is plain markup, not
one. Measured result: 65 -> 27 pages (Typst's own page-fill packs
tighter than ordo.tex's needspace-driven approach), one compile pass,
zero orphans.

The five non-paginated flavours (ms/html/md/adoc/txt) never had a
forced page break to remove -- they mainly needed the same header
treatment for structural consistency: a week-level header nested
under each month's existing one, walking months>weeks>days (the
week's own padded, in-month-guarded day list) in place of the old
months>days flat loop. Verified against groff, asciidoctor and an
HTML parser -- zero warnings.

Goldens regenerated through the Test_view.view_of path
test_render_golden.ml itself uses, not the CLI (whose --lang default
would have pinned output the tests never produce).
