compline: build the full hour, sharing Prime's resolver helpers

Ordo is Monastic 1617 as a base, with deliberate Tridentine 1906
additions: the "In manus tuas" short responsory, the Nunc Dimittis
with its "Salva nos" antiphon, the fuller Preces (Monastic's own is
shorter), and Lent's "Christe, qui lux es et dies" hymn replacement
(English translation marked draft, pending a real historical one).
Psalms 4, 90, 133 are fixed daily with real verified text, unlike
Prime's weekday-rotated psalms.

The closing Marian antiphon now picks Alma Redemptoris Mater / Ave
Regina Caelorum / Regina Caeli / Salve Regina by real season, using
the calendar work from the previous commit — except Ave Regina
Caelorum's own window (Candlemas through the day before Maundy
Thursday) doesn't align to any single season value, so that one case
checks the real date directly instead of going through the by-season
table.

resolve-common.ts extracts the resolve/status/doxology/antiphon
helpers Prime already had into something Compline can share; a few
propers files lose their "prime-" prefix now that both hours use them.

+# Verified against Divinum Officium (Tridentine 1906), 2026-08-25 run —
+# Monastic Compline doesn't have this at all (like Prime's borrowed
+# responsory); added by explicit choice. Uses the non-Dominican verse
+# ("Redemísti nos" / "us") — the Order of Preachers rubric substitutes
+# "Redemísti me" ("me") instead, not used here.
