propers: Benedictus antiphons for February's sanctoral entries (7/7)

5 authored fresh (Dorothea, Apollonia, Scholastica, Valentine,
Matthias), 2 corrected (Agatha, Chair of St. Peter at Antioch -- both
confirmed sourced from the Roman rite's raw [Ant 1] rather than a real
Monastic 1617 rendering, same pattern as January's corrections).

Two needed translation/rewording, not just transcription: Scholastica
had no English at all in the source (translated fresh, marked draft);
Matthias's own English existed but was jarringly modern next to every
other antiphon's archaic register, so reworded to match (the
underlying verse's standard Douay-Rheims wording) and marked draft
rather than presented as a straight source transcription.

Also noted in TODO.md, not fixed: splitNamedAntiphon always marks its
output verified regardless of input status, so a draft antiphon
currently renders as if fully verified wherever it's actually
displayed -- a pre-existing issue across every hour, only now surfaced
by content with a real draft status going through it.
