Add unconditional short litany before Matins collect

Reuses the existing lauds-short-litany proper (Kyrie eleison x3 + Pater
noster) rather than a Matins-named duplicate, same reuse discipline
Vespers already applies. Unlike Lauds/Vespers's own preces, this fires
every day with no ferial/Sunday swap and is never omitted.
