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).

+    It is commemorated the finding at Jerusalem in the time of the Emperor Constantine of the Most Holy Cross of the Lord.
+
+    Upon the same day, were born into the better life: At Rome, upon the Nomentan Way, the holy martyrs Pope Alexander I., [in the year 117,] and the priests Eventius and Theodulos. Under the Emperor Hadrian and the judge Aurelian, Alexander suffered chains and imprisonment, racking, tearing with hooks, and fire, and was at length put to death by small stabs over his whole body. Eventius and Theodulos were long imprisoned, then examined under torture by fire, and at last beheaded.
+
+    At Narni, [in the year 376,] the holy Confessor Juvenal, Bishop of that see.
+
+    At Constantinople, [in the year 313,] the holy martyrs Alexander the Soldier, and Antonina the Virgin. In the persecution under the Emperor Maximian the President Festus condemned her to a brothel Alexander awaited her there, changed clothes with her, and so enabled her to escape. For this reason they were put to the torture together, and when both had had their hands cut off, they were together cast into the fire for Christ's sake, and having so finished together their noble contending, were crowned together.
+
+    In the Thebaid, [about the year 286,] the holy martyrs Timothy and Myra his wife. The Prefect Arian, after putting them to diverse torments, ordered them to be crucified together. They hung upon the cross alive for nine days, the one strengthening the other in the faith, and so together at last finished their testimony.
+
+    At Aphrodisia, in Karia, [in the fourth century,] the holy martyrs Diodorus and Rodopian, who were stoned to death by their fellow-citizens during the persecution under the Emperor Diocletian.
+
+    Upon Mount Senario, near Florence, [in the thirteenth century,] the blessed Confessors Sosthenes and Uguccio, two of the seven founders of the Order of Servants of the Blessed Virgin Mary, who departed this life upon the same day and at the same hour, as they were repeating the angelic salutation, even as had been foretold to them from heaven.
