Add Lauds' ferial Preces (Tridentine 1906/1910), shown on ferial/vigil days

Monastic 1617 has no Preces feriales at Lauds at all -- content sourced
from Tridentine 1906/1910 per direct instruction, same track as the
Cross suffrage and St. Joseph's suffrage. New lauds-preces-feriales.yml
(Kyrie, Pater noster, the full versicle litany, Psalm 129, closing
versicles) transcribed from a live query against a clean Advent feria,
matching what actually rendered rather than the underlying template's
own conditional markup (the Pope/Bishop and benefactors' versicles are
both dropped live despite being present in the template; the King/nation
versicle pair is kept despite the template's own rubric note suggesting
otherwise).

New `lauds-preces` part kind (hours/types.ts) picks between this and the
existing short Sunday/feast litany (lauds-short-litany.yml, unchanged
content) on a ferial-or-vigil day. Deliberately not the shared
`isSundayOrFeast` predicate, which treats a Vigil as a "feast" -- here a
Vigil needs to land on the ferial side instead, per direct instruction.
Also deliberately wider than the real 1906/1910 rubric itself, which
restricts the fuller form to Advent/Lent/Ember days specifically -- shown
on *every* ferial or vigil day instead, mirroring the identical explicit
choice already made for Prime's own ferial Preces.
