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).

Hæc, sub Diocletiáno Imperatóre et Eutólmio Prǽside, cum multa pro Christo pertulísset, ipsum quoque Cypriánum, qui erat magus et suis mágicis ártibus eam dementáre conabátur, ad Christiánam fidem convértit; cum quo póstea martýrium sumpsit. Eórum córpora, feris objécta, rapuérunt noctu quidam nautæ Christiáni, et Romam detulérunt; quæ, póstmodum in Basílicam Constantiniánam transláta, prope Baptistérium cóndita sunt.

+    At Nicomedia, the holy martyrs Cyprian and Justina the Virgin. Justina suffered much for Christ's sake under Diocletian the Emperor and Eutholmius the President, and she converted to Christ the warlock Cyprian, who had sought by his magical arts to put her out of her mind, but along with whom she afterwards suffered martyrdom. Their bodies were cast out to be eaten by beasts, but certain Christian sailors took them by night and brought them to Rome, and they were afterwards taken to the church of the Most Holy Saviour, founded by the Emperor Constantine, where they are buried hard by the Baptistery.
+
+    At Rome, the holy martyrs Callistratus and forty-nine others, all soldiers. In the persecution under the Emperor Diocletian, Callistratus was sewn up in a leathern sack and cast into the sea, and when, by the help of God, he escaped unharmed, the others were converted to Christ and suffered martyrdom along with him.
+
+    Likewise at Rome, (in the year 310,) the holy Confessor Pope Eusebius.
+
+    At Bologna, (in the fifth century,) the holy Confessor Eusebius, Bishop (of that see.)
+
+    At Brescia, (in the sixth century,) holy Vigilius, Bishop (of that see.)
+
+    At Albano, holy Senator.
+
+    In the country of Frascati, (at the beginning of the eleventh century,) the blessed Abbot Nilus, a man of great holiness, Founder of the Monastery of Grotta-Ferrata, (of the Italian Congregation of the Order of St. Basil.)
+
+    At Citta di Castello, the holy Priest Amantius, famous for the grace of working miracles.
