Give temporal commemorations at Lauds/Vespers a real Ant+V/R+collect bundle

getDayCollects previously rendered a commemorated Sunday/privileged
feria (calendar/commemorations.ts's ordinary-sunday/privileged-sunday/
privileged-feria-minor branches) as a bare, unlabeled collect -- no
antiphon, no versicle, no indication it was even a commemoration. Only
sanctoral commemorations had gotten the fuller bundle treatment
(2026-08-30 pass). Adds temporalCommemorationPart, reusing the temporal
day's own benedictus/magnificat antiphon and weekday-keyed versicle (the
same content it would use had it won outright), falling back to a
labeled bare collect or honest "missing" block when no antiphon is
authored for that id.

Verified live for Nov 1, 2026 (All Saints on a Sunday): both Lauds and
Vespers now show "Commemoration of The 22nd Sunday after Trinity" with
real antiphon and versicle instead of a silent bare prayer.
