Author Ascension's own collect

A separate, pre-existing gap: getDayCollect already looked up
ascension-collect via resolveOfficeWinner (the same mechanism this
session's earlier fix already covers), but the content file itself
never existed. Live-verified against Divinum Officium (Monastic
Tridentinum 1617), 2026-05-14.

+    Concéde, quǽsumus, omnípotens Deus: ut, qui hodiérna die Unigénitum tuum, Redemptórem nostrum, ad cælos ascendísse crédimus; ipsi quoque mente in cæléstibus habitémus.
+    Per eúmdem Dóminum nostrum Jesum Christum Fílium tuum, qui tecum vivit et regnat in unitáte Spíritus Sancti, Deus, per ómnia sǽcula sæculórum.

+    Let us pray.
+    Grant, we beseech thee, Almighty God, that just as we do believe thine Only-Begotten Son, our Saviour, to have this day ascended into the heavens, so we may also in heart and mind thither ascend, and with Him continually dwell.
+    Through the same Jesus Christ, thy Son, Our Lord, Who liveth and reigneth with thee in the unity of the Holy Ghost, God, world without end.
+    R. Amen.
