calendar: add Christ the King, last Sunday of October

A 1925 addition, so nowhere in the Monastic Tridentinum 1617 base this
project otherwise targets -- content sourced from "Monastic Divino
1930" instead, the Monastic-lineage version of the era that actually
carries it. Always wins outright (Duplex I. classis, confirmed live),
commemorating whichever Sunday after Pentecost it displaces -- same
additive-layering shape as applyOctaves/applyMarianSaturday, run last
so nested commemorations (e.g. a Simplex saint already commemorated
under that Sunday) survive underneath it.

Extended the Lauds psalmody-override mechanism (both the psalm groups
and, newly, the chapter/responsory/hymn/versicle bundle) to recognize
named temporal winners as unconditionally override-eligible, not just
duplex-majus+ sanctoral ones -- generalizing what had been a Marian-
Saturday-only special case. Suffrages needed their own explicit check
too: isDoubleOrHigher only ever looks at a sanctoral rank, and a named
temporal winner has no FeastClass to check at all.
