Build the Vespers ordo: mechanism, weekday content, seasonal content

Wires resolveOrdo('vespers', ...) end to end: opening versicle,
weekday psalmody (4 groups, handling the joined Ps 115+116 and the
split Ps 138/143 via a PsalmRef-like shape), the chapter/responsory/
hymn/versicle office bundle, Magnificat, day-collects — reusing
resolveEveningDay so First/Second Vespers precedence and the cross-day
commemoration (both added in the previous commit) apply automatically
— and a closing that reuses Lauds' own conclusio, since no distinct
"Vespera" version of that exact text turned up in the source.

getMagnificatAntiphon mirrors getBenedictusAntiphon's saint/temporal-id
lookup order, but also falls back to real content Benedictus has no
equivalent of: the classic ferial set that quotes the Magnificat's own
text in sequence across the week, with the correct Monastic-rubric
variant picked for Tue/Thu/Fri/Sat (two of those needed a fresh
translation where the Monastic Latin diverges from the given English
in content, not just wording).

Also includes Vespers' own seasonal content (Advent/Lent/Passiontide/
Paschaltide chapter+responsory+hymn+versicle), transcribed from the
same source blocks as the weekday content, with the Monastic-specific
hymn variants hand-applied from the source's substitution notation
against each base Roman text (one transcription slip caught and fixed
mid-pass: the Passiontide hymn's closing lines had been copied from
the Roman text instead of the Monastic one actually being
transcribed). Passiontide's own responsory/hymn correctly omit the
Gloria Patri, matching real rubric and the source data as given.

All weekday/seasonal content marked `draft`, not `verified` — read
directly from the reference source, not cross-checked against a live
rendering per day the way the psalmody was.

Six other hours' resolvePart switches needed the three new HourPart
kinds ('vespers-psalmody', 'vespers-office', 'magnificat') added to
their exhaustive not-used lists so they still typecheck; three
pre-existing tests assumed Vespers was still "coming soon" and are
updated to exercise Matins (still the genuine stub) instead.

+# The classic ferial Magnificat-antiphon set: each weekday quotes the
+# Magnificat's own text in sequence (Monday = its opening verse, Tuesday =
+# the next, and so on through Saturday). Sourced from Divinum Officium's
+# Monastic block ("[Feria2 Ant 3]" through "[Feria7 Ant 3]", Psalterium/
+# Special/Major Special.txt). Sunday has no entry here on purpose — its own
+# source ("[Dominica Ant 3] = @:Dominica Ant 2 = /:ut in Proprio de
+# Tempore:/") draws from that specific Sunday's own Proper of the Time, not
+# a fixed weekly default; unauthored content for now (see
+# hours/resolve-common.ts's getMagnificatAntiphon).
+#
+# Four of the six weekdays have a real Monastic-specific Latin variant,
+# marked in the source "(sed rubrica tridentina aut rubrica monastica)" —
+# used here in place of the plain/Roman line above it, per direct
+# instruction to read this app's target rubric (pre-1955, Monastic
+# Tridentinum 1617) straight from these branch labels rather than treat
+# them as optional. The English source only tracks that same variant for
+# Saturday; Tuesday's only differs by a verb ending (no translation
+# impact), but Thursday's and Friday's Monastic Latin diverge from the
+# English enough in *content* (not just wording) that the given English
+# would misrepresent them — those two are translated fresh here instead,
+# marked `draft` for that reason specifically, not just the general
+# not-live-verified caveat the rest of this file carries.
