Add closing Gloria Patri after psalms, omitted during the Sacred Triduum

Psalms across every hour rendered with no closing Gloria Patri at all.
Add it centrally (hours/index.ts) rather than per-hour, using a new
calendar/temporal.ts isInTriduum helper so it's correctly dropped from
Maundy Thursday through Holy Saturday and nowhere else — live-verified
against both of this app's actual source tracks (Divino Afflatu 1954
and Tridentine 1906), not just the modern Rubrics 1960 default. Also
fixes Lauds' existing but Triduum-blind canticle Gloria Patri append.
