Author full Christmas-Octave Sunday content, fix a temporal-id override gap

christmas-octave-sunday previously had only its Benedictus antiphon
authored -- no Lauds psalmody override or office bundle, no Prime/Terce/
Sext/None content at all. Adds the full set: Lauds psalmody (3 psalms +
Canticle of the Three Young Men + Laudate, all distinct antiphons),
Lauds capitulum/versicle/hymn ("A solis ortus cardine"), and Prime/Terce/
Sext/None antiphons+chapters (Terce/Sext/None only, matching Gal
4:1-2/4:4-5/4:7 -- the same reading the raw Monastic Tridentinum 1617
source file gives for this Sunday).

Real code gap found and fixed along the way: getMinorHourOverrideId
(hours/resolve-common.ts) only checked the sanctoral branch of
resolveOfficeWinner's result, so a named temporal feast in
ALWAYS_OVERRIDE_TEMPORAL_IDS (marian-saturday, christ-the-king) got a
Lauds psalmody override but silently never a Prime/Terce/Sext/None one,
however much was authored for it. Fixed by mirroring
getPsalmodyOverrideFor's own temporal-id branch (hours/lauds.ts), and
christmas-octave-sunday added to that set.

Content sourced from a "Divino Afflatu 1954" live query rather than
Monastic Tridentinum 1617, since 1617 has no real identity of its own for
this Sunday under its own calendar rules on most Dec 26-29 dates (only
the collect, already authored separately, happened to be pulled from a
date where 1617 did render it) -- consistent with this app's stated
precedent of following D.A. for calendar/precedence even while keeping
1617's shape for the hours themselves elsewhere.
