Finish the last 5 vigils: weekday-keyed commemoration antiphons

Corrected an earlier "no source exists" claim by live-querying real
commemorated instances of the Vigils of St. Lawrence and the Assumption
across six different weekdays. Their source files' own [Rule] block
("Versum Feria") turns out to be a real, sourced mechanism, not an
absence: a mere commemoration doesn't reuse the vigil's own antiphon at
all -- it borrows the plain ferial day's antiphon/versicle instead, and
that antiphon quotes the Benedictus canticle in weekday sequence (same
shape vespers-magnificat-antiphons.yml already uses for the Magnificat).
The versicle is a single fixed text. Sunday has no entry: a Vigil
transfers off an ordinary Sunday rather than ever reaching a
commemoration there, confirmed live as well as already true in this
app's own precedence rules.

sanctoralCommemorationPart now takes weekday and resolves this
dynamically for common-of-a-vigil saints, rather than needing a static
per-saint file. All 218 saints with an authored collect now have a real
commemoration antiphon.

+# A mere commemoration of a Vigil (`common: common-of-a-vigil` — St.
+# Lawrence's, the Assumption's, All Saints', Ss. Simon and Jude's, St.
+# John the Baptist's) does NOT reuse that vigil's own antiphon (the one
+# used when it wins outright, e.g. vigil-of-st-lawrence-antiphon.yml) —
+# its own source file's [Rule] block says "Versum Feria" (borrow the
+# plain ferial day's own versicle/antiphon instead), confirmed live
+# (Monastic Tridentinum 1617): the Vigil of St. Lawrence's commemoration
+# on a real Monday (2027-08-09) and the Vigil of the Assumption's on six
+# different real weekdays (2026 Fri/2027 Sat/2028 Mon/2029 Tue/2030
+# Wed/2031 Thu) all gave the exact same result for their weekday — the
+# antiphon quotes the Benedictus canticle's own text in weekday sequence
+# (same "quote the framing canticle in order through the week" pattern
+# vespers-magnificat-antiphons.yml already uses for Vespers), same text
+# regardless of *which* vigil. Sunday has no entry: a Vigil (`FeastClass:
+# 'vigil'`, weaker than Semiduplex) never actually reaches a commemoration
+# on an ordinary Sunday in this app's own precedence rules either — it
+# transfers instead (calendar/commemorations.ts's `ordinary-sunday`
+# branch) — confirmed live too (2033-08-14, a real Sunday: the Vigil of
+# the Assumption doesn't appear at all, only the Lawrence-octave day is
+# commemorated).
+#
+# English: the reference engine's own English files have no translation
+# for this specific commemoration antiphon at all (checked across every
+# weekday) -- these are direct translations, informed by the Benedictus
+# canticle's own already-verified English (propers/common/benedictus.yml)
+# for vocabulary consistency, but not independently sourced -- `status`
+# marks them `draft` for that reason.
