Add October sanctoral content: 12 saints/feasts

Continues the full-year sanctoral import: the Guardian Angels (Duplex
majus, full proper content), St. Thérèse of Lisieux, St. Bruno, St.
Bridget of Sweden, St. Francis Borgia, the Maternity of the BVM (Duplex
II Classis, instituted 1931 for the 1500th anniversary of the Council
of Ephesus, full proper content), St. Edward the Confessor, St. Teresa
of Avila (distinct from St. Thérèse of Lisieux -- two different
Carmelite saints sharing a name), St. Margaret Mary Alacoque, St. Peter
of Alcantara, St. John Cantius, and St. Raphael the Archangel (own
full proper content, matching st-gabriel-archangel.yml's established
pattern for a Sancti file that redirects wholesale to another date's
file but still carries its own real content).

St. Raphael's new fixed day (Oct 24, Duplex majus) collided with the
"clean, empty Saturday" fixture used by three tests for Marian
Saturday/Lauds-psalmody-override behavior; moved all three to 2026-07-04,
verified genuinely free of any sanctoral entry (not even a commemorated
Simplex).

+    Deus, qui ineffábili providéntia sanctos Angelos tuos ad nostram custódiam
+    míttere dignáris: largíre supplícibus tuis; et eórum semper protectióne
+    deféndi, et ætérna societáte gaudére.

+    Spíritus Sancti, Deus, per ómnia sǽcula sæculórum.
+    ℟. Amen.

+    Let us pray.
+    O God, Who in thine unspeakable Providence hast been pleased to give
+    thine holy Angels charge over us, to keep us, mercifully grant unto our
+    prayers, that we be both ever fenced by their wardship here, and
+    everlastingly blessed by their fellowship hereafter.
+    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.
