Let a sanctoral winner's proper Matins psalmody win over a Sunday's

resolveOrdo's Sunday-nocturn branch fired unconditionally whenever
day.weekday === 'sunday', regardless of who actually won the day --
silently making any saint's own proper Matins psalmody override
(getMatinsSaintOverride) unreachable on a Sunday, even when authored.
The source's own "Psalmi Dominica" rubric line reads as if the plain
Sunday psalm cursus always applies whenever a Duplex+ feast wins over a
Sunday, but live-querying All Saints (Nov 1, 2026, a Sunday that year)
shows it actually has its own distinct proper psalms (Ps 1/4/8, 14/23/
31, 33/60/96, each its own antiphon) -- not the plain Sunday Nocturn
psalms this app was falling back to. Checks for a sanctoral proper
override before the Sunday branch now.

That override's own Nocturn 3 is psalms, not the 3-OT-canticle shape
every other saint/category file uses -- added renderOverrideNocturn3 to
dispatch on which field is actually populated instead of assuming
canticles unconditionally (which produced a silently empty antiphon and
no content).
