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).

+% A5, CONTINUOUS: days flow one after another with no forced page break per
+% week (Defect 2 -- the original one-week-per-page layout filled roughly
+% the top third of every page and cost 65 pages for a year that needed far
+% fewer; that requirement is reversed here on purpose, not merely relaxed).
+% Structure stays scannable through two header weights instead: every
+% week still opens with its existing small header line ({{month_name}} .
+% {{term.week}} N), and the month's own FIRST week additionally gets a
+% large, ruled banner above that line ({{#first}}...{{/first}}, a real
+% view field -- lib/render/view.ml -- not template-side arithmetic, since
+% this engine has no way to test "is this the first item" any other way).
+% \needspace (a genuine, tiny dependency, not one of the deps this project
+% freezes at the OCaml level -- LaTeX packages are a template author's own
+% concern) keeps a header from being stranded alone at a page's bottom
+% with its first day box pushed to the next one: 29mm covers the month
+% banner's own rule+title (~11.5mm) plus the week header below it
+% (~5.5mm) plus room for at least one day box (~10mm); 16mm covers just
+% the week header plus one day box. Both re-verified against the actual
+% typeset output, not derived from theory alone (the task report has the
+% before/after page counts and a scan proving no header is ever left
+% alone at a page's foot with nothing under it).
+%
+% \label fires AFTER both \needspace calls below, not before: a \label
+% placed before a \needspace that goes on to force a break captures the
+% OLD page number (\thepage at the point \label is processed, not where
+% its content actually lands) -- a step-stale \pageref found live in an
+% early draft's own TOC (week 3 read "page 3" while its own content
+% demonstrably started on page 4). Moving the label to fire only once the
+% page a week ACTUALLY starts on is already decided fixes it at the
+% source, cheaper than a third pdflatex pass, which would not have fixed
+% it either (the wrong page number was already committed to the .aux by
+% the second pass).
+%
+% Each day in a framed box with a colour swatch, tightened from an
+% earlier draft (top/bottom padding 0.4mm, before skip 0.5mm, \scriptsize
+% meta text, rank/colour and the citations on separate lines) for this
+% same continuous flow: a full 7-day week already occupies most of an A5
+% page even at reduced size (measured: 55-65% of the text height for a
+% typical week, more with commemorations), so simply dropping the forced
+% per-week \clearpage only let the year's many PARTIAL boundary weeks
+% double up, not full ones -- a real but small saving on its own. Three
+% changes together fit a genuinely useful second (often third, on a short
+% week) week onto the same page: \fontsize explicitly (not \scriptsize,
+% whose 7pt/8.4pt leading is looser than a dense booklet needs), the
+% feast name still a clearly-bolder 9pt, and rank/colour folded onto the
+% SAME line as the citations rather than a line of its own -- an A5 box
+% is far wider than it is tall (roughly 120mm of usable width here), so
+% "I classis . albus  Epistola ... Evangelium ..." fits with room to
+% spare even on Holy Week's own longest citations (measured against the
+% rendered output, not assumed; see the task report for the page count
+% this bought).
+%
+% Every fixed string (headings, the Epistle/Gospel/Commemoration/Week
+% labels) comes from the view's term vocabulary rather than being written
+% into this file, so a translated booklet needs no template edit -- only
+% a different --lang.
