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).

+    At Perga, in Pamphylia, [in the year 251,] blessed Nestor, Bishop [of Magydensis.] During the persecution under Decius he was instant in prayer by day and by night that Christ's flock might be kept safe. When he was arrested he confessed the name of the Lord with wonderful freedom and readiness. By command of the President Pollio he was most cruelly racked, and as he steadfastly declared that he would alway cleave unto Christ, he was at last crucified, and from the cross passed to heaven a conqueror.
+
+    At Perga likewise, [in 251,] the holy martyrs Papias, Diodorus, Conon, and Claudian, who suffered before holy Nestor.
+
+    Also the holy martyrs Fortunatus Felix, and twenty-seven others.
+
+    At Alexandria, [in the year 326,] the glorious Elder, holy Alexander, Pope of that see, wherein he succeeded blessed Peter. He it was who cast his priest Arius out of the church when he became perverted with wicked heresy, and reprobate from the truth of God, and he was afterward one of the three hundred and eighteen fathers who condemned him in the Council of Nicea.
+
+    At Bologna, [in the fourth century,] the holy Bishop [of that see,] Faustinian, who by the preaching of the word of God strengthened and increased that Church when it had been troubled in the persecution under the Emperor Diocletian.
+
+    At Gaza, in Palestine, [in the year 420,] holy Porphyry, Bishop of that see, who in the time of the Emperor Arcadius cast down the idol Mama and its temple, and after many sufferings fell asleep in the Lord.
+
+    At Florence, [in the fifth century,] the holy Confessor Andrew, Bishop of that city, [who succeeded St. Zenobius.]
+
+    In the country of Troyes, [Vitre, in Champagne, in the sixth century,] the holy Confessor Victor, [Victor of Plancy, Priest and Hermit,] whose praises have been written by holy Bernard.
