propers: add November's collect and antiphon text

9 collects, 3 antiphons -- including backfilling the pre-existing All
Saints entry. Also updates two pre-existing tests whose shared date
(2025-11-30, Advent I Sunday) now correctly shows St. Andrew commemorated
alongside it, confirmed against the live reference engine.
