calendar: add Christ the King, last Sunday of October

A 1925 addition, so nowhere in the Monastic Tridentinum 1617 base this
project otherwise targets -- content sourced from "Monastic Divino
1930" instead, the Monastic-lineage version of the era that actually
carries it. Always wins outright (Duplex I. classis, confirmed live),
commemorating whichever Sunday after Pentecost it displaces -- same
additive-layering shape as applyOctaves/applyMarianSaturday, run last
so nested commemorations (e.g. a Simplex saint already commemorated
under that Sunday) survive underneath it.

Extended the Lauds psalmody-override mechanism (both the psalm groups
and, newly, the chapter/responsory/hymn/versicle bundle) to recognize
named temporal winners as unconditionally override-eligible, not just
duplex-majus+ sanctoral ones -- generalizing what had been a Marian-
Saturday-only special case. Suffrages needed their own explicit check
too: isDoubleOrHigher only ever looks at a sanctoral rank, and a named
temporal winner has no FeastClass to check at all.

+    Vexílla Christus ínclita
+    Late triúmphans éxplicat:
+    Gentes adéste súpplices,
+    Regíque regum pláudite.
+
+    Non Ille regna cládibus:
+    Non vi metúque súbdidit
+    Alto levátus stípite,
+    Amóre traxit ómnia.
+
+    O ter beáta cívitas
+    Cui rite Christus ímperat,
+    Quæ jussa pergit éxsequi
+    Edícta mundo cǽlitus!
+
+    Non arma flagrant ímpia,
+    Pax usque firmat fœ́dera,
+    Arrídet et concórdia,
+    Tutus stat ordo cívicus.
+
+    Servat fides connúbia,
+    Juvénta pubet íntegra,
+    Pudíca florent límina
+    Domésticis virtútibus.
+
+    Optáta nobis spléndeat
+    Lux ista, Rex dulcíssime:
+    Te, pace adépta cándida,
+    Adóret orbis súbditus.
+
+    Glória tibi, Dómine,
+    Qui sceptra mundi témperas,
+    Cum Patre, et Sancto Spíritu,
+    In sempitérna sǽcula.
+    Amen.

+    Christ's flag unfurled in glory raised,
+    Triumphing o'er the serpent's stings;
+    Come humbly forward all ye lands,
+    Applauding the great King of kings.
+
+    No force or threat doth he need use,
+    Not by coersion leadeth he;
+    Raised on the cross he draweth all,
+    With love unto his fruitful tree.
+
+    O! Thrice blest city of the Lord,
+    Wherein Christ ruleth without dearth;
+    Fervently she doth execute
+    His heavenly edicts to the earth,
+
+    No fiery weapon can e'er harm,
+    The peace 'stablished by Jesus' hand;
+    In happiness and unity,
+    The ranks of Christ secure do stand.
+
+    A marriage blessed by faith in thee,
+    Yields virtuous offspring from the womb;
+    Like seed in fertile soil doth grow,
+    In virtuous homes do children bloom.
+
+    We yearn and long to shine on us,
+    Thy light, O sweet and winsome King;
+    All thus submitted to thy reign,
+    To us, thy gift of peace do bring.
+
+    All glory be, Jesu, to thee,
+    Thy scepter over all that be;
+    All glory, as is ever meet,
+    To Father and to Paraclete.
+    Amen.
