feat(render): citations render through Sigla at both call sites

View.citation_ref and readings' part_ref are the only two places a
citation reaches output; every emitter goes through View.

--raw passes Sigla.verbatim rather than a style built over Lang.raw:
an identity name table would still reformat punctuation and renumber.

Loosen reject_sigla_for: --sigla-style/--sigla-book/--sigla-tradition
now actually render on readings/table/render/emit/publish (each
builds its own Sigla.t via the new load_sigla), and stay refused only
on commands that render no citation (day, easter, temporal, ...).

names_of degrades a Lang.bible miss to Book.default_spelling rather
than printing the lookup key itself ("luke.abbr"); pinned in cli.t
against a language file with no [bible] section at all, independent
of la.ini/en.ini's own eventual [bible] section.

Regenerate the 11 golden templates for 2027: every changed line is
one canonical citation replacing a stored variant, verified against
the full readings 2027 diff (raw vs default) cell by cell -- 86
distinct (raw, rendered) pairs account for the entire diff across all
11 files, with zero unexplained residue. Two families: the seven
duplicate book spellings collapsing onto one canonical form (Isa./Isa,
3 Kgs./3 Kings, ...), and citations reconstructed from parsed
structure dropping stray punctuation the parser already treats as
noise (a trailing period or semicolon, a comma chapter/verse
separator, an elided inherited chapter) -- each of the latter already
named and tested in test_citation.ml's parse_suite before this task.

+from lectio onto one canonical form (`3 Kgs.`/`3 Kings` -> `3 Kings`,
