Fix octave-day office content: use the octave's own feast, not the plain ferial

Real, multi-part bug found by looking closely at today's rendering (day 3
of St. Lawrence's octave, St. Clare commemorated): the psalmody
antiphons, hymn, chapter/responsory/versicle, Benedictus antiphon, and
day collect were all keyed off `day.winner` directly, which stays the
plain temporal identity (post-pentecost-11) throughout an octave --
St. Lawrence's own already-authored psalmody override and collect never
engaged on any day but his actual feast day. Live-verified (Tridentine
1910, 2026-08-12) that the whole office on an ordinary octave day
actually comes from the octave's own feast ("{ex Commune aut Festo}" /
"{ex Proprio Sanctorum}"), with a *weaker* commemorated saint (Clare)
getting a separate Ant+V/R+collect block of her own alongside it.

Fixed with a new resolveOfficeWinner(day) in hours/resolve-common.ts,
used everywhere getDayCollect/getDayCollects/getBenedictusAntiphon/
getPsalmodyOverrideFor used to read day.winner directly. Deliberately
gated on temporalCategory === 'ordinary-feria' (the day has no standing
of its own) rather than "any active octave" -- the Christmas Octave's
own stacked octaves are the live-verified counterexample where the
*temporal* day keeps the office instead, each octave becoming its own
separate commemoration block (not yet modeled, flagged in TODO.md).

Also fixes the ferial Preces gate (added in the previous commit) to
exclude active octaves the same way the suffrages already do --
live-verified "Preces Feriales{omittitur}" on the same date.

getDayCollects now renders a sanctoral commemoration as a real
Ant+V/R+collect bundle when authored (${propers}-commemoration.yml),
not just a bare, unlabeled collect -- the old rendering was indeed the
confusing "PRAYER / (translation pending)" block spotted today, which
was St. Clare's placeholder with no indication whose it was or why.
Authored her real commemoration bundle and standalone collect from the
same live query rather than leaving it pending.

One correction to a guess floated mid-session: the Benedictus antiphon
does NOT go to the commemorated saint (Clare) -- live-verified it stays
with the octave's own feast (Lawrence's "In cratícula"), same as
everything else in the primary office; only the separate commemoration
block is Clare's.
