Import St. Agatha's own proper Lauds/Vespers chapter

Live-verified against Divinum Officium (Monastic Tridentinum 1617),
2026-02-05: only the chapter is genuinely her own (Sir 51:1-3,
"Confitébor tibi, Dómine, Rex"). Responsory, hymn, and versicle are all
byte-identical to Common-of-a-Virgin-Martyr's own already-authored
content -- duplicated under her own id.
