Include the canticle's own citation in Lauds' resolved output

canticleText() built the resolved text/status from the weekday
canticle's verses but never copied the source YAML's own citation
field across, so every Lauds canticle rendered with no book/chapter/
verse citation at all despite the data already carrying one.
