Add Preces (Kyrie/Pater Noster + short litany) to Terce, Sext, and None

Real Monastic 1617 has no Preces at the Little Hours, and that was
previously documented as intentional. Per this project's "not a
reconstruction" design, Prime was recently given Preces in the secular
Tridentine form as a deliberate deviation from Monastic — do the same
here: the reference engine's ferial minor-hour Preces (Kyrie, Pater
Noster, then "Domine Deus virtutum, converte nos..." V/R pairs) is
authored as a single shared common id and wired into all three hours
after the chapter. By explicit choice this is said every day regardless
of rank, mirroring Prime's own "every ferial day" simplification, rather
than importing the reference engine's Sunday/feast form, whose sourcing
(a V/R block reused from Compline) looks like a data quirk rather than
genuine minor-hour content.
