propers: Benedictus antiphons for March's sanctoral entries (5/6)

4 authored fresh (Lucius I, Thomas Aquinas, the Forty Holy Martyrs,
Gregory the Great), 1 corrected (Joseph -- confirmed sourced from the
Roman rite's raw [Ant 1] rather than a real Monastic 1617 rendering,
same pattern as January/February's corrections).

Gregory the Great's antiphon (the "non Angli sed Angeli" episode) had
no English in the source at all -- translated fresh, marked draft.

St. Frances of Rome left honestly missing: Simplex rank, and her day
(March 9) falls within Lent in every year tested 2026-2035, so she can
never win outright under this app's own privileged-feria-major rule --
there's no live-rendered antiphon to source, ever, not just this year.
