Keep a short litany + Our Father at Compline on a Double, don't omit

compline-preces.yml was already the secular Tridentine 1906/1910 text
word-for-word (verified live against both tracks), so no text change
was needed there. The actual gap: both Monastic and secular tracks drop
Compline's Preces to nothing on a Double-or-higher, unlike Vespers/Lauds
which fall back to a short form. Per explicit request, this is now a
deliberate vu-specific deviation from both tracks: on a Double, Compline
substitutes the same short Kyrie/Pater-Noster litany Vespers already
falls back to on Sundays/feasts, instead of showing nothing.
