Add Te decet laus to Matins, drop Ps 129/50 from ferial Preces

Matins now sings "Te decet laus" (Psalterium/Common/Prayers.txt's [Te
decet]) immediately after the Te Deum on every 3-nocturn day, matching
Rule of Benedict ch. 11's close of Vigils. New common text
te-decet-laus.yml, wired into both matins.ts branches that render a Te
Deum; absent on ferial days along with it.

Also drops Psalm 129 (De profundis) from the Lauds ferial Preces and
Psalm 50 (Miserere) from the Vespers ferial Preces, per direct
instruction — both were embedded inline in the live-transcribed text.
Updated the affected fixture tests to key off a versicle that survives
the removal instead of the now-absent psalm text.
