feat(lang): Latin and English book names, and the shipped sigla styles

la.ini and en.ini both gain [sigla] (the current Vulgate/Latin punctuation
convention, byte-identical to Render.default_style) and [bible] (a .full
and .abbr row for every id in Book.all -- 45 cited ids plus the 7 tradition
targets, 52 total). Shipping [sigla] changes no output, asserted by the
full test run. Shipping [bible] does change rendered book names, which is
the point.

la.ini's titles are sourced from docs/research/scan1.txt/scan2.txt (the
1962 Missal scans), each row citing the line its incipit pattern was read
from. Six pairs (kings_3/4, corinthians_1/2, thessalonians_1/2,
timothy_1/2, peter_1/2) share one Missal incipit and differ only in the
sourced .abbr, matching what the primary text itself does. Three ids
(proverbs, song_of_songs, ecclesiasticus) and the seven tradition targets
are marked UNSOURCED and fall back to the data's own spelling, per this
project's central rule against inventing a Latin title.

Re-running the task's own sourcing note against the scans, counting every
hit rather than eyeballing a frequency-sorted list, found nine of its
NOT-sourced verdicts were undercounted (a single clean hit, buried under
higher-frequency matches): Galatians, Colossians, both Thessalonians, both
Peter, Malachi, Numbers, Jonas, Osee and Esdras all have a clean incipit
in the scans and are sourced here. The note's other three verdicts stand,
confirmed independently. Ecclesiasticus is not simply unfound: this Missal
reuses Wisdom's own Lectio libri Sapientiae incipit for Ecclesiasticus
readings too (both were anciently classed as one Sapiential group), so
using it for Ecclesiasticus would misidentify the book, not merely
abbreviate it -- recorded in that row's own comment.

en.ini's [bible] is filled in full, not left partial the way [celebration]
is: without it, a Vulgate-numbered id would fall through the [meta]
fallback chain to la.ini's Latin name, not merely a less complete English
one. Traditional Douay-Rheims names for the Vulgate ids (3 Kings, Osee,
Ecclesiasticus, Isaias, Apocalypse), modern names for the seven tradition
targets, since --sigla-tradition modern is the reader asking for modern
numbering.

test_lang_coverage.ml gains test_every_book_named, asserting every
Book.all id has both forms in la.ini -- the check that catches a forgotten
tradition target, since nothing else in the suite ever names them.

Shipping real book names changes 11 golden template renders (Render/golden)
and several test/cli.t examples that used to demonstrate the pre-Task-10
default-spelling fallback; both are updated to the new, correct output,
each line checked against a fresh render before promoting.
