Bulk-author sanctoral commemoration antiphon+versicle bundles

Found that 217 of 220 saints with an authored collect had no
${propers}-commemoration.yml bundle, so sanctoralCommemorationPart was
silently falling back to a bare collect with no antiphon whenever that
saint was merely commemorated rather than winning outright (user-reported
for St. Raymond Nonnatus and the Decollation of St. John the Baptist).

Bulk-fixed: reused each saint's own proper antiphon where authored, else
the standard de-Communi [Ant 2]/[Versum 2] for that saint's own Common
category. Confirmed via three already live-verified commemorations
(Ss. Felix and Adauctus, St. Clare, St. Sabina) that [Ant 2]/[Versum 2]
are the real tags used for a mere commemoration, not [Ant 1]/[Nocturn 2
Versum] as first assumed -- corrected St. Raymond Nonnatus's file
accordingly. 182 of ~218 real saints now covered; entries not
independently live-verified are marked draft. Remaining ~36 (BVM feasts,
angels, confessor-doctors/popes, vigils) tracked in TODO.md.

New tests/propers/commemoration-sweep.test.ts (182 cases) asserts every
bundle has a real antiphon+versicle+collect, never bare/missing.
