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 beátum Petrum Confessórem tuum admirábilis pœniténtiæ et
+    altíssimæ contemplatiónis múnere illustráre dignátus es: da nobis,
+    quǽsumus; ut, ejus suffragántibus méritis, carne mortificáti,
+    facílius cæléstia capiámus.
+    Per Dóminum nostrum Jesum Christum, Fílium tuum: qui tecum vivit et regnat in unitáte
+    Spíritus Sancti, Deus, per ómnia sǽcula sæculórum.
+    ℟. Amen.

+    Let us pray.
+    O God, Who hast been pleased to set before us in thy blessed
+    Confessor Peter a wondrous example of penance and of a mind
+    unfathomably rapt in thee, let, we beseech thee, the same thy
+    servant pray for us, and him do Thou accept, that we may so die unto
+    earthly things, as to take lively hold on heavenly things.
+    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.
