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.

+    Deus, qui nos ánnua beáti Cleméntis Mártyris tui atque Pontíficis solemnitáte lætíficas: concéde propítius; ut cujus natalítia cólimus, virtútem quoque passiónis imitémur.
+    Per Dóminum nostrum Jesum Christum, Fílium tuum: qui tecum vivit et regnat in unitáte Spíritus Sancti, Deus, per ómnia sǽcula sæculórum.

+    Let us pray.
+    O God, Who dost gladden us by the yearly Feast-day of thine holy Martyr, Clement mercifully grant unto us who keep their birthday, the strength to imitate their patience under suffering.
+    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.
