Import the Purification's own proper Lauds/Vespers chapter

Live-verified against Divinum Officium (Monastic Tridentinum 1617),
2026-02-02 (fixed date, always winnable): only the chapter is genuinely
her own (Mal 3:1, "Ecce ego mitto Angelum meum"). Responsory, both
hymns, and both versicles are all byte-identical to Common-of-the-BVM's
own already-authored content -- duplicated under her own id.
