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.

+    Hail holy Queen, Mother of Mercy, our life, our sweetness, and our hope. To thee do we cry, poor banished children of Eve. To thee do we send up our sighs, mourning and weeping in this valley of tears. Turn then, most gracious Advocate, thine eyes of mercy toward us. And after this our exile show unto us the blessed fruit of thy womb, Jesus. O clement, O loving, O sweet Virgin Mary.
+
+    V. Pray for us, O Holy Mother of God.
+    R. That we may be made worthy of the promises of Christ.
+
+    Let us pray.
+    O almighty, everlasting God, who by the cooperation of the Holy Spirit, didst prepare the body and soul of Mary, glorious Virgin and Mother, to become a worthy dwelling for Thy Son; grant that we who rejoice in her commemoration may, by her gracious intercession, be delivered from present evils and from everlasting death. Through the same Christ our Lord. Amen.
