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.

+    Vexílla Regis pródeunt:
+    Fulget Crucis mystérium,
+    Quo carne carnis Cónditor
+    Suspénsus est patíbulo.
+
+    Quo vulnerátus ínsuper
+    Mucróne diro lánceæ,
+    Ut nos laváret crímine,
+    Manávit unda et sánguine.
+
+    Impléta sunt quæ cóncinit
+    David fidéli cármine,
+    Dicens: In natiónibus
+    Regnávit a ligno Deus.
+
+    Arbor decóra et fúlgida,
+    Ornáta Regis púrpura,
+    Elécta digno stípite
+    Tam sancta membra tángere.
+
+    Beáta, cujus bráchiis
+    Sæcli pepéndit prétium,
+    Statéra facta córporis,
+    Prædámque tulit tártari.
+
+    O Crux, ave, spes única,
+    In hac triúmphi glória
+    Hoc Passiónis témpore
+    Auge piis justítiam,
+    Reísque dona véniam.
+
+    Te summa, Deus, Trínitas,

+    Abroad the regal banners fly,
+    Now shines the cross's mystery;
+    Upon it Life did death endure,
+    And yet by death did life procure.
+
+    Who, wounded with a direful spear,
+    Did, purposely to wash us clear
+    From stain of sin, pour out a flood
+    Of precious water mixed with blood.
+
+    That which the prophet-king of old
+    Hath in mysterious verse foretold,
+    Is now accomplished, whilst we see
+    God ruling nations from a tree.
+
+    O lovely and refulgent tree,
+    Adorned with purpled majesty;
+    Culled from a worthy stock, to bear
+    Those limbs which sanctified were.
+
+    Blest tree, whose happy branches bore
+    The wealth that did the world restore;
+    The beam that did that body weigh
+    Which raised up hell's expected prey.
+
+    O Cross, our one reliance, hail!
+    On this triumphant day avail,
+    This holy Passiontide,
+    To give fresh merit to the saint,
+    And pardon to the penitent.
+
+    Blest Trinity, salvation's spring,
+    May every soul thy praises sing;
+    To those thou grantest conquest by
+    The holy cross, rewards apply.
+    Amen.
