feat: naming, localisation and the rebuilt printed output

colitur computed the calendar correctly and could not say what it had
computed. A printed ordo read ef-septuagesima-sunday-2 where a reader
expects Dominica in Sexagesima, and the wall calendar showed slugs in
every cell.

  lib/naming    a language table and a config file, both pure and total,
                parsing the INI reader Overlay_ini already had
  lang/         la.ini and en.ini -- 725 names, every one transcribed
                from the 1962 Missal and citing the line it came from
  templates     the ordo rebuilt as an A5 booklet: one week per page, a
                table of contents, framed days, a colour swatch; the wall
                calendar now fills its sheet instead of a quarter of it
  tools         check_citations.py verifies all 400 citations resolve,
                with 33 self-tests of its own

Names resolve through lang -> declared fallback -> the slug, so a partial
translation is usable from its first line and the fully degraded case is
the old output rather than a blank page.

colitur day and colitur readings are BYTE-IDENTICAL to before, verified
against main rather than asserted; --lang, --raw and the lang/config
subcommands are still to come, and man/colitur-templates.5 still
documents the pre-naming view, so writing a custom template needs the
source until that lands.
