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.

+    Ætérna cæli glória,
+    Beáta spes mortálium,
+    Celsi Tonántis Únice,
+    Castǽque proles Vírginis:
+
+    Da déxteram surgéntibus,
+    Exsúrgat et mens sóbria,
+    Flagrans et in laudem Dei
+    Grates repéndat débitas.
+
+    Ortus refúlget Lúcifer,
+    Sparsámque lucem núntiat:
+    Cadit calígo nóctium:
+    Lux sancta nos illúminet.
+
+    Manénsque nostris sénsibus,
+    Noctem repéllat sǽculi,
+    Omníque fine diéi
+    Purgáta servet péctora.
+
+    Quæsíta jam primum fides
+    Radícet altis sénsibus:
+    Secúnda spes congáudeat,
+    Qua major exstat cáritas.
+
+    Deo Patri sit glória,
+    Ejúsque soli Fílio,
+    Cum Spíritu Paráclito,
+    Et nunc, et in perpétuum.
+    Amen.

+    O Christ, whose glory fills the heaven,
+    Our only hope, in mercy given;
+    Child of a Virgin meek and pure;
+    Son of the Highest evermore:
+
+    Grant us thine aid thy praise to sing,
+    As opening days new duties bring;
+    That with the light our life may be
+    Renewed and sanctified by thee.
+
+    The morning star fades from the sky,
+    The sun breaks forth; night’s shadows fly:
+    O Thou, true Light, upon us shine:
+    Our darkness turn to light divine.
+
+    Within us grant thy light to dwell;
+    And from our souls dark sins expel;
+    Cleanse thou our minds from stain of ill,
+    And with thy peace our bosoms fill.
+
+    To us strong faith forever give,
+    With joyous hope, in thee to live;
+    That life’s rough way may ever be
+    Made strong and pure by charity.
+
+    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.
