propers: transcribe Lauds' fixed and weekday content

Every fixed and weekday-variable text Lauds needs beyond the psalms/
canticles themselves: per-weekday antiphons (data/hours/lauds-
antiphons.yml, reconstructed with an embedded '*' from the engine's
separately-rendered incipit/full lines), the weekday capitulum/
responsory/hymn/versicle bundle (shared verbatim Mon-Fri for the
capitulum, confirmed against the live engine), the fixed Benedictus
text, the Kyrie/Pater-noster short litany, the four Tridentine
suffrages, the conclusio, and the closing versicle.

Saturday's hymn is left honestly `missing`: every ordinary-time
Saturday is either Marian-Sabbato-overridden or falls in a privileged
season whose hymn is itself swapped for the season's own, so there's
no achievable date showing a genuinely per-annum, unprivileged
Saturday Lauds hymn to source it from.
