Prime: real content (psalms, Martyrology, Regula) and ordo corrections

Pulls in verified content from Divinum Officium rather than placeholders:
17 psalms (2, 6, 7-19, 118, 129), 365 days of the Martyrology, and the full
121-reading Regula cycle, plus the Athanasian Creed.

Ordo corrections driven by review against the real engine output:
- Capitulum and Preces now pick a Sunday/feast vs. ferial form
  (calendar/isSundayOrFeast); ferial Preces said every ferial day by choice.
- Chapter responsory, hymn doxology, and the opening versicle's
  Alleluia/Laus tibi all vary by season via a shared resolver
  (hours/seasonal-propers.ts).
- Real Roman Kalends/Nones/Ides Latin dating (calendar/roman-date.ts,
  verified against 363/365 real Martyrology headings) plus the historical
  "bis sextus" Feb 29 handling, and the Martyrology's Luna (moon-day)
  heading (a ported Golden-Number calculation).
- Fixed responsory structure (was missing its initial full repeat),
  weekday psalm antiphons (opening as incipit-or-full by rank, full
  repeat after the psalms/Creed as its own part, "*" chant mark kept),
  scripture citations on the capitulum/lectio brevis, and V./R. markers
  switched from Unicode symbols to plain text for reliable font rendering.
- Dropped Pretiosa and the dead-commemoration psalm (129) for time;
  trimmed section headings down to the ones that are actually named
  things (Preces, Chapter Office, etc. no longer relabel connective text).

+    Quicúmque vult salvus esse, * ante ómnia opus est, ut téneat cathólicam fidem:
+    Quam nisi quisque íntegram inviolatámque serváverit, * absque dúbio in ætérnum períbit.
+    Fides autem cathólica hæc est: * ut unum Deum in Trinitáte, et Trinitátem in unitáte venerémur.
+    Neque confundéntes persónas, * neque substántiam separántes.
+    Alia est enim persóna Patris, ália Fílii, * ália Spíritus Sancti:
+    Sed Patris, et Fílii, et Spíritus Sancti una est divínitas, * æquális glória, coætérna majéstas.
+    Qualis Pater, talis Fílius, * talis Spíritus Sanctus.
+    Increátus Pater, increátus Fílius, * increátus Spíritus Sanctus.
+    Imménsus Pater, imménsus Fílius, * imménsus Spíritus Sanctus.
+    Ætérnus Pater, ætérnus Fílius, * ætérnus Spíritus Sanctus.
+    Et tamen non tres ætérni, * sed unus ætérnus.
+    Sicut non tres increáti, nec tres imménsi, * sed unus increátus, et unus imménsus.
+    Simíliter omnípotens Pater, omnípotens Fílius, * omnípotens Spíritus Sanctus.
+    Et tamen non tres omnipoténtes, * sed unus omnípotens.
+    Ita Deus Pater, Deus Fílius, * Deus Spíritus Sanctus.
+    Et tamen non tres Dii, * sed unus est Deus.
+    Ita Dóminus Pater, Dóminus Fílius, * Dóminus Spíritus Sanctus.
+    Et tamen non tres Dómini, * sed unus est Dóminus.
+    Quia, sicut singillátim unamquámque persónam Deum ac Dóminum confitéri christiána veritáte compéllimur: * ita tres Deos aut Dóminos dícere cathólica religióne prohibémur.
+    Pater a nullo est factus: * nec creátus, nec génitus.
+    Fílius a Patre solo est: * non factus, nec creátus, sed génitus.
+    Spíritus Sanctus a Patre et Fílio: * non factus, nec creátus, nec génitus, sed procédens.
+    Unus ergo Pater, non tres Patres: unus Fílius, non tres Fílii: * unus Spíritus Sanctus, non tres Spíritus Sancti.
+    Et in hac Trinitáte nihil prius aut postérius, nihil majus aut minus: * sed totæ tres persónæ coætérnæ sibi sunt et coæquáles.
+    Ita ut per ómnia, sicut jam supra dictum est, * et únitas in Trinitáte, et Trínitas in unitáte veneránda sit.
+    Qui vult ergo salvus esse, * ita de Trinitáte séntiat.
+    Sed necessárium est ad ætérnam salútem, * ut Incarnatiónem quoque Dómini nostri Jesu Christi fidéliter credat.
+    Est ergo fides recta ut credámus et confiteámur, * quia Dóminus noster Jesus Christus, Dei Fílius, Deus et homo est.
+    Deus est ex substántia Patris ante sǽcula génitus: * et homo est ex substántia matris in sǽculo natus.
+    Perféctus Deus, perféctus homo: * ex ánima rationáli et humána carne subsístens.
+    Æquális Patri secúndum divinitátem: * minor Patre secúndum humanitátem.
+    Qui licet Deus sit et homo, * non duo tamen, sed unus est Christus.
+    Unus autem non conversióne divinitátis in carnem, * sed assumptióne humanitátis in Deum.
+    Unus omníno, non confusióne substántiæ, * sed unitáte persónæ.
+    Nam sicut ánima rationális et caro unus est homo: * ita Deus et homo unus est Christus.
+    Qui passus est pro salúte nostra: descéndit ad ínferos: * tértia die resurréxit a mórtuis.
+    Ascéndit ad cælos, sedet ad déxteram Dei Patris omnipoténtis: * inde ventúrus est judicáre vivos et mórtuos.
+    Ad cujus advéntum omnes hómines resúrgere habent cum corpóribus suis; * et redditúri sunt de factis própriis ratiónem.
+    Et qui bona egérunt, ibunt in vitam ætérnam: * qui vero mala, in ignem ætérnum.
+    Hæc est fides cathólica, * quam nisi quisque fidéliter firmitérque credíderit, salvus esse non póterit.

+    Whosoever willeth to be saved, * before all things it is necessary that he hold the Catholic faith.
+    Which faith except every one do keep whole and undefiled, * without doubt he shall perish eternally.
+    Now the Catholic faith is this, * that we worship one God in Trinity, and Trinity in Unity.
+    Neither confounding the Persons, * nor dividing the substance.
+    For there is one Person of the Father, another of the Son, * and another of the Holy Ghost.
+    But the Godhead of the Father, of the Son, and of the Holy Ghost is one, * the Glory Equal, the Majesty Co-Eternal.
+    Such as the Father is, such is the Son, * and such is the Holy Ghost.
+    The Father Uncreated, the Son Uncreated, * and the Holy Ghost Uncreated.
+    The Father Infinite, the Son Infinite, * and the Holy Ghost Infinite. * The Father Eternal, the Son Eternal, * and the Holy Ghost Eternal.
+    And yet they are not three Eternals, * but one Eternal.
+    As also they are not three Uncreated, nor three Infinites, * but One Uncreated, and One Infinite.
+    So likewise the Father is Almighty, the Son Almighty, * and the Holy Ghost Almighty.
+    And yet they are not three Almighties, * but One Almighty.
+    So the Father is God, the Son God, * and the Holy Ghost God.
+    And yet they are not three Gods, * but One God.
+    So the Father is Lord, the Son Lord, * and the Holy Ghost Lord.
+    And yet they are not three Lords, * but One Lord.
+    For, like as we are compelled by Christian truth to acknowledge every Person by Himself to be God and Lord, * so are we forbidden by the Catholic Religion to say, there be three Gods or three Lords.
+    The Father is made of none, * neither created, nor begotten.
+    The Son is of the Father alone: * not made, nor created, but begotten.
+    The Holy Ghost is of the Father, and the Son: * not made, nor created, nor begotten, but proceeding.
+    So there is One Father, not three Fathers; one Son, not three Sons; * one Holy Ghost, not three Holy Ghosts.
+    And in this Trinity is nothing afore or after, nothing is greater or less; * but the whole three Persons are Co-Eternal together, and Co-Equal.
+    So that in all things, as is aforesaid, * the Unity in Trinity, and the Trinity in Unity is to be worshipped.
+    He therefore that willeth to be safe, * let him thus think of the Trinity.
+    But it is necessary to eternal salvation, * that he also believe faithfully the Incarnation of our Lord Jesus Christ.
+    The right Faith therefore is, that we believe and confess, * that our Lord Jesus Christ, the Son of God, is God and man.
+    God, of the Substance of the Father, Begotten before the worlds: * and Man, of the substance of His mother, born in the world.
+    Perfect God, Perfect Man, * of a reasoning soul and human flesh subsisting.
+    Equal to the Father as touching His Godhead, * inferior to the Father as touching His Manhood.
+    Who, although He be God and Man, * yet He is not two, but One Christ.
+    One, however, not by conversion of the Godhead into Flesh, * but by taking of the Manhood into God.
+    One altogether, not by confusion of Substance, * but by Unity of Person.
+    For as the reasoning soul and flesh is one man, * so God and man is One Christ.
+    Who suffered for our salvation, descended into hell, * rose again the third day from the dead.
+    He ascended into heaven, He sitteth on the right hand of the Father, God Almighty, * from whence He shall come to judge the quick and the dead.
+    At whose coming all men shall rise again with their bodies, * and shall give account for their own works.
+    And they that have done good shall go into life eternal, * but they that have done evil into eternal fire.
+    This is the Catholic Faith, * which except a man believe faithfully and firmly, he cannot be safe.
