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).

+    Sicut est zelus amaritúdinis malus qui séparat a Deo et ducit ad inférnum, ita est zelus bonus qui séparat a vítia et ducit ad Deum et ad vitam ætérnam. Hunc ergo zelum ferventíssimo amóre exérceant mónachi, id est ut honóre se ínvicem prævéniant, infirmitátes suas sive córporum sive morum patientíssime tólerent, obœdiéntiam sibi certátim inpéndant: nullus quod sibi útile júdicat sequátur, sed quod magis álio; caritátem fraternitátis caste inpéndant. Amóre Deum tímeant. Abbátem suum sincéra et húmili caritáte díligant. Christo omníno nihil præpónant, qui nos páriter ad vitam ætérnam perdúcat.

+    Just as there is an evil zeal of bitterness which separates from God and leads to hell, so there is a good zeal which separates from vices and leads to God and to life eternal. By most fervent love therefore let monks exercise this zeal, that is, let them see to it that in honour they prefer one another. Let them most patiently tolerate their infirmities whether physical or of character; let them compete in yielding obedience; let none follow what he judges convenient to himself, but rather what he judges convenient to another; in chaste love let them exercise fraternal charity; let them fear God; let them love their abbot with sincere and humble affection; on no account let them exalt anything above Christ; and may He bring us all alike to eternal life.
