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.

-    Psalm 50.
-    Have mercy on me, O God, according to thy great mercy.
-    And according to the multitude of thy tender mercies blot out my iniquity.
-    Wash me yet more from my iniquity, and cleanse me from my sin.
-    For I know my iniquity, and my sin is always before me.
-    To thee only have I sinned, and have done evil before thee: that thou mayst be justified in thy words, and mayst overcome when thou art judged.
-    For behold I was conceived in iniquities; and in sins did my mother conceive me.
-    For behold thou hast loved truth: the uncertain and hidden things of thy wisdom thou hast made manifest to me.
-    Thou shalt sprinkle me with hyssop, and I shall be cleansed: thou shalt wash me, and I shall be made whiter than snow.
-    To my hearing thou shalt give joy and gladness: and the bones that have been humbled shall rejoice.
-    Turn away thy face from my sins, and blot out all my iniquities.
-    Create a clean heart in me, O God: and renew a right spirit within my bowels.
-    Cast me not away from thy face; and take not thy holy spirit from me.
-    Restore unto me the joy of thy salvation, and strengthen me with a perfect spirit.
-    I will teach the unjust thy ways: and the wicked shall be converted to thee.
-    Deliver me from blood, O God, thou God of my salvation: and my tongue shall extol thy justice.
-    O Lord, thou wilt open my lips: and my mouth shall declare thy praise.
-    For if thou hadst desired sacrifice, I would indeed have given it: with burnt offerings thou wilt not be delighted.
-    A sacrifice to God is an afflicted spirit: a contrite and humbled heart, O God, thou wilt not despise.
-    Deal favourably, O Lord, in thy good will with Sion; that the walls of Jerusalem may be built up.
-    Then shalt thou accept the sacrifice of justice, oblations and whole burnt offerings: then shall they lay calves upon thy altar.
