feat(templates): week headers stop repeating the month name

Every ordo booklet week header used to print the month name again
even though the month heading right above it already established it
-- pure noise, repeated once per week for the whole year. All seven
ordo flavours now print the week's own Roman numeral plus the span of
dates it covers instead, e.g. "Hebdomada I (Ian 1-2)", with no month
name on the line; the LaTeX table of contents and the Typst outline
(built automatically from its own headings, so editing the heading is
the whole fix there) read the same way.

A single-day week (e.g. a lone trailing Sunday) renders "Ian 31", not
"Ian 31-31": each flavour's dash sits inside an inverted single_day
section, so the engine -- which cannot itself compare first_dom to
last_dom -- never has to decide anything, it only follows the data.
The dash character matches each flavour's own existing convention:
LaTeX/Typst's own "--" ligature, groff's \(en escape (alongside its
existing \(bu), HTML's – entity (alongside its existing
·), and a literal en dash for the three flavours with no
escaping (adoc/md/txt).

Every in-template comment describing the new fields is written without
ever typing two curly braces together, including in the two comments
this touches that used to embed a live {{month_name}}/{{term.week}}
tag pair inside a LaTeX % comment -- harmless only because that whole
line already started with %, not because the engine has any comment
awareness (it has none).

Goldens regenerated through test_render_golden.ml's own render path
(Test_view.view_of + Template.render_string), not the CLI -- the two
differ in default language and would otherwise pin output the test
suite never produces. Grid goldens are untouched, matching the grid
templates, which have no week header.

Verified against real pdflatex (two passes) and typst compile output,
not merely the golden pins: both flavours print "Hebdomada I (Ian
1-2)", "Hebdomada II (Ian 3-9)", "Hebdomada III (Ian 10-16)" as their
first three week headers and identical text in the table of
contents/outline, and both show "Hebdomada VI (Ian 31)" for January's
own trailing single-day week with no dash.
