Fix Vespers ferial psalmody weekday bug, add duplex-majus+ Common psalmody override

Vespers psalms on Mon-Sat were silently following the anticipated
First-Vespers day's weekday instead of the actual calendar date's, since
resolvePsalmody reused resolveEveningDay's result (correct for
propers/office, which legitimately borrow tomorrow's identity, but wrong
for the ferial psalm cycle, which has no per-feast override of its own).

Also adds a duplex-majus+ Common-category psalmody override to both
Lauds and Vespers, mirroring Matins' existing saint/category mechanism.
Lauds already had a per-feast-only override; Vespers had none. 8 of 24
Common categories authored for both hours, live-verified against the
reference engine.
