propers: Benedictus antiphons for August's sanctoral entries (12/12)

9 authored fresh (Dominic, Ss. Cyriacus/Largus/Smaragdus, Assumption,
Bernard, Bartholomew, Louis, Zephyrinus, Augustine), 1 corrected
(Peter's Chains -- confirmed sourced from the Roman rite's raw [Ant 1]
rather than a real Monastic 1617 rendering, same pattern as every
month so far). Two already matched the live query as found (Finding
of St. Stephen, the Decollation of St. John the Baptist) and needed no
change.

Bartholomew needed the same register fix as Matthias/Barnabas/James
the Greater (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.
