Author Matins hymns for the categories/saints from this session's Lauds/Vespers pass

resolveMatinsHymn (hours/matins.ts) is a separate mechanism from
resolveOfficeBundle, with its own fallback chain (proper -> active
octave -> Common via SaintRecord.common -> season -> ferial). Only the
Confessor family and Apostle had a matins-hymn-<id>.yml before this
pass; everything else fell through to season/ferial at Matins
specifically, even after the Lauds/Vespers fixes.

Live-verified and authored: common-of-several-martyrs ("Ætérna Christi
múnera, Et Mártyrum victórias"), common-of-an-abbot and
common-of-several-confessors (= Confessor-Not-Bishop's hymn, same label
finding as Lauds/Vespers), common-of-a-virgin-martyr/-virgin ("Vírginis
Proles"), common-of-a-holy-woman/-widow (a genuinely shorter closing-two-
stanzas form, "Hujus obténtu, Deus alme"), Guardian Angels/St.
Michael/St. Gabriel/St. Raphael (reused from St. Michael's Apparition,
confirmed via SanctiM/05-08.txt's own cross-reference), common-of-the-
bvm ("Quem terra, pontus, ǽthera"), Finding/Exaltation of the Holy Cross
("Pange, lingua, gloriósi," the Nativity-themed other half of the same
poem as Lauds' own hymn), and the Transfiguration (byte-identical to its
own Vespers hymn).

+    Vírginis Proles, Opiféxque Matris,
+
+    Virgo quem gessit, peperítque Virgo:
+
+    Vírginis festum cánimus trophǽum
+
+    Accipe votum.
+
+
+    Hæc tua Virgo dúplici beáta
+
+    Sorte, dum gestit frágilem domáre
+
+    Córporis sexum, dómuit cruéntum
+
+    Corpóre sæclum.
+
+
+    Unde nec mortem, nec amíca mortis
+
+    Sæva pœnárum génera pavéscens,
+
+    Sánguine fuso méruit sacrátum
+
+    Scándere cælum.
+
+
+    Hujus obténtu, Deus alme, nostris
+

+
+    Quo tibi puri resonémus almum
+

+    Son of a virgin, maker of thy mother,
+
+    Thou, rod and blossom from a stem unstainèd,
+
+    While we a Virgin's triumphs are rehearsing,
+
+    Hear our petition!
+
+
+    Lo, on thy handmaid fell a two-fold blessing,
+
+    Who, in her body vanquishing the weakness,
+
+    In that same body, grace from heaven obtaining,
+
+    Bore the world witness.
+
+
+    Death, nor the rending pains of death appalled her;
+
+    Bondage and torment found her undefeated:
+
+    So by the shedding of her blood attained she
+
+    Heavenly guerdon.
+
+
+    Fountain of mercy, hear the prayers she offers;
+
+    Purge our offences, pardon our transgressions,
+
+    So that hereafter we to thee may render
+
+    Praise with thanksgiving.
+
+
+    Thou, the All-Father, thou, the One-Begotten,
+
+    Thou, Holy Spirit, Three in One co-equal,
+
+    Glory be henceforth thine through all the ages,
+
+    World without ending. Amen.
