propers: Benedictus antiphons for September's sanctoral entries (5/5)

4 authored fresh (Matthew, Ss. Cyprian and Justina, Ss. Cosmas and
Damian, Jerome), 1 corrected (the Nativity of the BVM -- confirmed
sourced from the Roman rite's raw [Ant 1] rather than a real Monastic
1617 rendering, same pattern as every month so far).

Matthew needed the same register fix as Matthias/Barnabas/James the
Greater/Bartholomew (Matt 19:27ff, same verse): the source's own
English existed but read jarringly modern next to everything else,
reworded to match and marked draft.
