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).

+    Alexandríæ sanctórum Mártyrum Epímachi et Alexándri, qui, sub Décio Imperatóre, cum fuíssent multo témpore in vínculis, atque, divérsis supplíciis affécti, perdurássent in fide, ígnibus tandem consúmpti sunt. Sanctus vero Epímachus, simul cum sancto Gordiáno Mártyre, festíva celebritáte cólitur sexto Idus Maji.
+
+    Romæ sancti Synésii Mártyris, qui, beáti Xysti Papæ Secúndi témpore ordinátus Lector, et, cum multos convertísset ad Christum, apud Aureliánum Imperatórem accusátus, martýrii corónam gládio percússus accépit.
+
+    Eódem die sanctórum Mártyrum Hermógenis, Donáti et aliórum vigínti duórum.
+
+    Tréviris sanctórum Mártyrum Maxéntii, Constántii, Crescéntii, Justíni et Sociórum; qui in persecutióne Diocletiáni, sub Rictiováro Prǽside, passi sunt.
+
+    Alexandríæ sanctárum Ammonáriæ Vírginis, Mercúriæ, Dionýsiæ et altérius Ammonáriæ. Harum prima, in persecutióne Décii, inaudítis tormentórum genéribus superátis, beátum vitæ finem, ferro cædénte, percépit; tres vero áliæ, cum Judex a féminis superári erubésceret, ac dubitáret, ne, eádem in illas exércens cruciaménta, viríli eárum étiam constántia vincerétur, statim jussæ sunt decollári.

+    At Rome, the holy martyr Synesius, who was ordained a Reader in the time of the blessed Pope Xystus, and converted many to Christ he was accused before the Emperor Aurelian, and received the crown of martyrdom by being beheaded, (in the year 270.)
+
+    At Alexandria, under the Emperor Decius, the holy martyrs Epimachus and Alexander; they were long kept in chains and put to diverse torments, but they persevered in the faith, and at the last were burnt, (in the year 250.)
+
+    Likewise at Alexandria, the holy women Ammonaria the Virgin, Mercuria, Dionysia, and another called also Ammonaria. In the aforesaid persecution under the Emperor Decius, the first of these died a blessed death by the sword, after overcoming torments unheard of. The judge was ashamed to be conquered by women, and shrank from causing the application to them of the same tortures as to the first, and so conquered by their steadfastness, ordered them to be beheaded, (in the year 250.)
+
+    On the same day, the holy martyrs Hermogenes, Donatus, and twenty-two others.
+
+    At Trier, (in the fourth century,) under the President Rictiovarus, in the persecution under the Emperor Diocletian, suffered the holy martyrs Maxentius, Constantius, Crescentius, Justinus, and their Companions.
