Render Lauds/Matins canticle titles bilingually

English used the same id-derived Latin title (e.g. "Canticum Ezechiae")
for every language. Now English uses the authored name from
lauds-canticles.ts when one exists, falling back to the derived title
for names already conventional untranslated in English (Benedictus,
Magnificat, Nunc Dimittis) and Matins' scripture-ref-derived ids.
