Author Common-of-a-Virgin-Martyr / Common-of-a-Virgin Lauds/Vespers bundle

Live-verified against Divinum Officium (Monastic Tridentinum 1617)
votive=C6: chapter 2 Cor 10:17-18, hymn "Jesu, coróna Vírginum" (byte-
identical Lauds/Vespers), shared versicle "Diffúsa est grátia in lábiis
tuis" -- only the two responsories differ between the hours. Cross-
checked plain common-of-a-virgin (St. Praxedes) renders the same real
content, matching the already-existing benedictus-antiphon-common-of-a-
virgin.yml precedent -- duplicated the same 7 files under that id too.

Proof: St. Apollonia's own clean year (2029-02-09, her 2026 date collides
with St. John of Matha) for Lauds, St. Praxedes's real First-Vespers
anticipation for Vespers.
