Switch Prime's Sunday/feast Preces to the secular Tridentine form

Monastic Prime's own Dominicales Preces drop the "Et ego ad te, Domine,
clamavi..." versicle block and shorten the closing "Miserere nostri,
Domine... Fiat misericordia tua..." set. Prefer the secular Tridentine
form instead (live-verified against Divinum Officium's "Tridentine -
1906" version), keeping "beato Patri nostro Benedicto" in the Confiteor
by explicit choice even though the real secular Confiteor omits it.

The Sunday/ferial by-day-kind split stays as-is; the ferial form
(prime-preces-feriales.yml) is unchanged and continues to show on every
ferial day by deliberate choice, more generously than the historical
rubric.
