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.

+    Splendor patérnæ glóriæ,
+    De luce lucem próferens,
+    Lux lucis, et fons lúminis,
+    Diem dies illúminans:
+
+    Verúsque sol illábere,
+    Micans nitóre pérpeti:
+    Jubárque Sancti Spíritus
+    Infúnde nostris sénsibus.
+
+    Votis vocémus et Patrem,
+    Patrem perénnis glóriæ,
+    Patrem poténtis grátiæ,
+    Culpam reléget lúbricam.
+
+    Confírmet actus strénuos:
+    Dentes retúndat ínvidi:
+    Casus secúndet ásperos,
+    Donet geréndi grátiam.
+
+    Mentem gubérnet et regat,
+    Casto, fidéli córpore:
+    Fides calóre férveat,
+    Fraudis venéna nésciat.
+
+    Christúsque nobis sit cibus,
+    Potúsque noster sit fides:
+    Læti bibámus sóbriam
+    Ebrietátem spíritus.
+
+    Lætus dies hic tránseat,
+    Pudor sit ut dilúculum,
+    Fides velut merídies,
+    Crepúsculum mens nésciat.
+
+    Auróra cursus próvehit,
+    Auróra totus pródeat,
+    In Patre totus Fílius,
+    Et totus in Verbo Pater.
+
+    Deo Patri sit glória,
+    Ejúsque soli Fílio,
+    Cum Spíritu Paráclito,
+    Et nunc et in perpétuum.
+    Amen.

+    O splendour of God’s glory bright,
+    O thou that bringest light from light,
+    O light of light, light’s living spring,
+    O day, all days illumining.
+
+    O thou true sun, on us thy glance
+    Let fall in royal radiance,
+    The Spirit’s sanctifying beam
+    Upon our earthly senses stream.
+
+    The Father too our prayers implore,
+    Father of glory evermore,
+    The Father of all grace and might,
+    To banish sin from our delight:
+
+    To guide whate’er we nobly do,
+    With love all envy to subdue,
+    To make ill-fortune turn to fair,
+    And give us grace our wrongs to bear.
+
+    Our mind be in his keeping placed,
+    Our body true to him and chaste,
+    Where only faith her fire shall feed,
+    And burn the tares of Satan’s seed.
+
+    And Christ to us for food shall be,
+    From him our drink that welleth free,
+    The Spirit’s wine, that maketh whole,
+    And mocking not, exalts the soul.
+
+    Rejoicing may this day go hence,
+    Like virgin dawn our innocence,
+    Like fiery noon our faith appear,
+    Nor know the gloom of twilight drear.
+
+    Morn in her rosy car is borne;
+    Let him come forth our perfect morn,
+    The Word in God the Father One,
+    The Father perfect in the Son.
+
+    All laud to God the Father be;
+    All praise, Eternal Son, to thee;
+    All glory, as is ever meet,
+    To God the Holy Paraclete.
+    Amen.
