Add St. Francis de Sales, St. Martina, St. John Bosco (Jan 29-31)

Per direct instruction to import all available sanctoral content
regardless of rubric-era markers: these three had real, complete Matins
content in the reference engine and were simply never added during the
earlier month-by-month sanctoral pulls (no exclusion comment, no
placeholder -- just never reached). First of a broader sweep across the
whole calendar.

New shared Common template: benedictus-antiphon-common-of-a-confessor.yml
(Commune/C5's own Ant 1) -- the first common-of-a-confessor saint that
needed one; st-alexius.yml (the only prior user of this category) had
used a Cistercian-specific alternate instead.

npm test (365 tests) and tsc --noEmit both pass.

+    Deus, qui sanctum Joánnem Confessórem tuum adolescéntium patrem et magístrum excitásti,
+    ac per eum, auxiliatríce Vírgine María, novas in Ecclésia tua famílias floréscere
+    voluísti: concéde, quǽsumus; ut eódem caritátis igne succénsi, ánimas quǽrere, tibíque
+    soli servíre valeámus.
+    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 didst raise up thy blessed Confessor John, to be a father and teacher of
+    youth, and didst will that through him, with the help of the Virgin Mary, new families
+    should flourish in the Church, grant we pray that enkindled with the same fire of
+    charity we may be strong to seek after souls and to serve thee alone.
+    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.
