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).

+    Si quis abbas sibi presbýterum vel diáconem ordinári petíerit, de suis elégat qui dignus sit sacerdótio fungi. Ordinátus autem cáveat elatiónem aut supérbiam, nec quicquam præsúmat nisi quod ei ab abbáte præcípitur, sciens se multo magis disciplínæ regulári subdéndum. Nec occasióne sacerdótii obliviscátur régulæ obœdiéntiam et disciplínam sed magis ac magis in Deum profíciat. Locum vero illum semper adténdat quod ingréssus est in monastério, præter offícium altáris, et si forte eléctio congregatiónis et volúntas abbátis pro vitæ mérito eum promovére volúerint. Qui tamen régulam decánis vel præpósitis constitútam sibi serváre sciat. Quod si áliter præsúmpserit, non sacérdos sed rebéllio judicétur. Et sæpe admónitus si non corréxerit, étiam epíscopus adhibeátur in testimónio. Quod si nec sic emendáverit, clarescéntibus culpis, proiciátur de monastério, si tamen talis fúerit ejus contumácia ut subdi aut obœdíre régulæ nolit.

+    If any abbot should wish to provide a priest or deacon for his monastery, let him choose from among his own monks one who is worthy to exercise the priesthood. And let the one ordained beware of self-importance and pride; and let him not presume to do anything except it be ordered him by the abbot, knowing himself much more subject to the discipline of the rule. And let him not on account of his priesthood be forgetful of the obedience and discipline of the rule, but let him progress in the Lord more and more. And let him always take that place which is his by seniority in the monastery, except as regards his service of the altar and unless by chance the choice of the community and the will of the abbot be pleased to promote him for his meritorious life; and even so let him know that the rules appointed him by the deans and provosts must be kept. But if he shall have presumed to act otherwise, let him be judged not as a priest but as rebellious; and if oft admonished he shall not correct himself, let the bishop himself at length be notified: but if even so he have not amended, his faults being manifest, let him be cast forth from the monastery, but only provided his contumacy shall have been such that he will not be subject to nor obey the rule.
