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 Verona, the holy martyr Zeno, Bishop [of that see,] which he governed with admirable faithfulness amid the storms of persecution. He was crowned with martyrdom in the time of the Emperor Gallienus.
+
+    In Cappadocia, the holy martyr Saba the Goth, who was put to grievous torments and then drowned in the river, when Athanaric, king of the Goths, was persecuting the Christians under the Emperor Valens. At the which time, according to holy Augustine, very many orthodox Goths won the crown of martyrdom.
+
+    At Braga, in Portugal, [about the year 300, under Diocletian,] the holy martyr Victor. He was only as yet preparing for baptism, when he refused to worship an idol, and with great faithfulness confessed Christ Jesus, for the which cause he was put to many torments and beheaded, and so obtained baptism in his own blood.
+
+    At Fermo, in Picenum, the holy Virgin and martyr Vissia.
+
+    At Rome, upon the Aurelian Way, holy Pope Julius [I.], who contended stoutly for the Catholic Faith against the Arians, and after many eminent acts fell asleep in peace, [in the year 352,] famous for holiness.
+
+    At the town of Gap, the holy Confessor Constantine, Bishop [of that see, about the year 455.]
+
+    At Pavia, holy Damian, Bishop of that see, [about the years 671-710.]
