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.
