Add per-feast Vespers office overrides for all 30 duplex-majus+ ids

Same eligibility rule as Lauds' psalmody override (a duplex-majus+
saint, or a named temporal feast), factored out to
resolve-common.ts's getOfficeOverrideId since Vespers has no
psalmody-override table of its own to piggyback eligibility on.

Authored via one live command=prayVespera query per id, reusing the
same clean per-saint dates already established for each one's Lauds
office-bundle override. The capitulum turned out to be byte-identical
between Lauds and Vespers for every one of the 30 ids checked, a real
Monastic-rite fact rather than a coincidence — so no
vespers-capitulum-<id>.yml files exist at all; the chapter falls
through to the already-authored lauds-capitulum-<id> directly instead
of duplicating identical content.

St. Scholastica's Vespers responsory, hymn, and versicle needed a hand
translation (same gap she has at Lauds/Terce/Sext/None — the reference
engine has no English for any of her proper content). Two more
one-line English gaps in the shared Immaculate Conception/Nativity of
the BVM responsory were filled with the standard Douay-Rheims/Ave
Maria wording.
