fix(naming): the rite prints its display name, not the internal id ef

The booklet's title page and running header read "Ordo 2027 . ef" --
an internal identifier reaching a reader, the same defect class the
sanctoral/temporal slugs were already fixed for.

lang/la.ini and lang/en.ini each gain a [rite] section mapping the
rite id to a reader-facing name, sourced from the Missal's own title
page (docs/research/LT.txt:6 "MISSALE ROMANUM", :15 "EDITIO TYPICA")
plus the 1962 dating this project uses throughout (rules-register.md,
CLAUDE.md) -- both cited in the ini comments, marked PATTERN since the
phrase combines two title-page elements rather than quoting one
verbatim heading.

Lang.t gains a rite table/lookup (same total, miss-echoes-the-key
contract as every other lookup here); View.of_days exposes rite_name
alongside the existing rite field, which stays the stable key exactly
as slug is kept beside name. Every shipped template that printed
{{rite}} now prints {{rite_name}} instead.

test_lang_coverage.ml gains a coverage assertion over every rite id
the engine can emit -- one today -- so a second rite module (OF)
landing without a matching [rite] entry fails loudly instead of
printing its own bare id.

Goldens regenerated through the Test_view.view_of path
test_render_golden.ml itself uses (English with a Latin fallback),
not the CLI (whose --lang default is plain Latin and would have
pinned output the tests never produce). test/cli.t's own JSON prefix
assertion updated to match: rite_name is a real new key in that
generic view dump, sitting right after rite.
