propers: Benedictus antiphons for July's sanctoral entries (9/9)

8 authored fresh (the Seven Brothers/Rufina/Secunda, Symphorosa and
Her Seven Sons, Margaret of Antioch, Apollinaris, James the Greater,
Anne, Nazarius/Celsus/Victor I/Innocent I, Abdon and Sennen), 1
corrected (Mary Magdalene -- confirmed sourced from the Roman rite's
raw [Ant 1] rather than a real Monastic 1617 rendering, same pattern
as every month so far).

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