Import Finding/Exaltation of the Holy Cross's own proper Lauds/Vespers content

Fully proper feast, live-verified against Divinum Officium (Monastic
Tridentinum 1617), 2027-05-03 for the Finding (its own 2026 date
collides with a privileged Sunday) and 2026-09-14 for the Exaltation.
Own chapter (Phil 2:5-7), own distinct responsory/hymn/versicle at each
hour -- Lauds hymn "Lustris sex qui jam peráctis," Vespers hymn "Vexílla
Regis pródeunt," both with real Alleluias baked into their own text
(confirmed permanent via the Vespers hymn's own "In hoc Pascháli gáudio"
line, not seasonal contamination).

Authored under two ids (finding-of-the-holy-cross and proper-to-the-
finding-of-the-holy-cross): Exaltation's own saint file sets common:
proper-to-the-finding-of-the-holy-cross, a different id than its propers
field (a separate day-collect/antiphon lookup) -- without the second
copy, resolveOfficeBundle fell through to the ferial default for her.
