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.

+    Audi, benígne Cónditor,
+    Nostras preces cum flétibus,
+    In hoc sacro jejúnio
+    Fusas quadragenário.
+
+    Scrutátor alme córdium,
+    Infírma tu scis vírium:
+    Ad te revérsis éxhibe
+    Remissiónis grátiam.
+
+    Multum quidem peccávimus,
+    Sed parce confiténtibus:
+    Ad laudem tui nóminis
+    Confer medélam lánguidis.
+
+    Sic corpus extra cónteri
+    Dona per abstinéntiam,
+    Jejúnet ut mens sóbria
+    A labe prorsus críminum.
+
+    Præsta, beáta Trínitas,

+    O kind Creator, bow thine ear
+    To mark the cry, to know the tear
+    Before thy throne of mercy spent
+    In this thy holy fast of Lent.
+
+    Our hearts are open, Lord, to thee:
+    Thou knowest our infirmity;
+    Pour out on all who seek thy face
+    Abundance of thy pardoning grace.
+
+    Our sins are many, this we know;
+    Spare us, good Lord, thy mercy show;
+    And for the honour of thy name
+    Our fainting souls to life reclaim.
+
+    Give us the self-control that springs
+    From discipline of outward things,
+    That fasting inward secretly
+    The soul may purely dwell with thee.
+
+    We pray thee, Holy Trinity,
+    One God, unchanging Unity,
+    That we from this our abstinence
+    May reap the fruits of penitence.
+    Amen.
