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.

+    O God, Who year by year dost gladden thy people by the solemn feast of thy blessed Virgin and Martyr Cecilia, grant unto us, we beseech thee, not only devoutly to observe the same, but also to follow after the pattern of her godly conversation.
+    Through Jesus Christ, thy Son our Lord, Who liveth and reigneth with thee, in the unity of the Holy Ghost, God, world without end.
+    ℟. Amen.
