Author Prime/Terce/Sext/None antiphons+chapters for all 29 duplex-majus+ saints

Completes the P/T/S/N minor-hour override backlog started with St. Lawrence:
every duplex-majus+ saint not blocked by a missing collect (propers: null)
now has its own antiphon (all four hours) and chapter (Terce/Sext/None) text,
live-verified against Divinum Officium (Monastic Tridentinum 1617).

Two saints needed corrections to the reference engine's own data rather than
straight extraction: St. Scholastica's minor hours have no English rendering
in the source at all (English/SanctiM only covers Matins for her), so the
English is translated here directly and marked draft; the Immaculate
Conception's antiphons render with diacritics stripped relative to the
word-for-word-parallel Nativity BVM antiphon, so accentuation is restored
to match and marked draft. Several saints share identical Common of Apostles
or Common of the BVM content, confirmed via diff before reuse.
