propers: add octave Matins readings, starting with St. Lawrence's

Adds propers/octave-readings.ts: a day-indexed lookup
(getOctaveReading(octaveId, dayNumber), id convention
"${octaveId}-octave-day-${dayNumber}") since readings genuinely vary day
to day within a single octave (confirmed: the Assumption's own octave
gives different patristic excerpts on day 2 vs. day 5) -- the singular
OctaveConfig.readingId field from the previous commit didn't fit that
reality and is removed.

Sourced via a different query command (prayMatutinum, not prayTertia)
than every other proper this pull has pulled -- the raw per-date
Sancti/MM-DD.txt files for octave-continuation days are occupied by
unrelated later-calendar saints (same trap as everywhere else), but the
real content lives in MM-DDoct.txt/MM-DDbmv.txt-style variant files the
live engine resolves correctly.

Per project convention (2026-08 discussion): the historical 3 (or 9-12,
on a day's own higher-rank office) Lectios are collapsed into one
continuous reading rather than kept broken up, and only the first
responsory is kept (which one to use when several collapse into one is
still an open question). A caught bug along the way: several readings
have no English translation in the source at all -- its own English page
silently falls back to showing the Latin text under the "Reading"
header, which an early pass mistakenly stored as a duplicate before the
mismatch was caught; now left honestly missing instead.

St. Lawrence's octave: real readings for days 2-5 and 8 (day 8, "In
Octava S. Laurentii," is a fuller distinct office); days 6-7 (Aug 15-16)
belong entirely to the Assumption's feast and octave instead -- day 7's
query, redirected, became assumption-octave-day-2's reading. The other
five octaves (Assumption's remaining days, Nativity BVM, Immaculate
Conception, All Saints, the Christmas trio, Pentecost) are follow-up
work, not done in this pass.

+    Sermo sancti Augustíni Epíscopi. Serm. 30. de Sanctis. Beatissimi Laurentii Martyris, cujus natalem hodie celebramus, passionem nosse vos credo: et quanta in persecutione pertulerit, dilectionem vestram scire posse non dubito. Tanta enim ejus martyrii gloria exstitit, ut passione sua mundum illuminaverit universum. Illuminavit mundum plane Laurentius eo lumine, quo ipse accensus est, et flammis quas ipse pertulit, omnium Christianorum corda calefecit.
+
+    Quis nolit ad horam uri Laurentii igne, ut æternum gehennæ non patiatur incendium? Beati igitur Laurentii exemplo provocamur ad martyrium, et accendimur ad fidem, incalescimus ad devotionem: et si in nobis persecutoris flamma deest, fidei tamen flamma non deest. Non ardemus quidem corpore pro Christo, sed ardemus affectu: non subjicit mihi persecutor ignem: sed suggerit mihi ignem desiderium Salvatoris.
+
+    Esse autem Salvatoris ignem legimus in Evangelio, dicente eodem Domino: Nescitis quia veni ignem mittere in terram? Et quid volo, nisi ut accendatur? Quo igne succensi illi duo discipuli dixerunt: Nonne cor nostrum ardens erat in nobis, dum loqueretur in via, et aperiret nobis Scripturas? Hoc igitur igne beatus Laurentius accensus, flammarum non sentit incendium: et dum Christi ardet desiderio, persecutoris pœnam non sentit.

+    From the Sermons of St. Augustine, Bishop of Hippo. 30th on the Saints I believe that ye know the history of the sufferings of that most blessed Martyr, Lawrence, whose birth-day we are keeping this day, and I doubt not, my beloved brethren, but that ye may know what agonies he endured under the persecutors. So illustrious is the glory of his martyrdom, that the splendour thereof shineth throughout the whole world. And this light, which Lawrence maketh so clearly to shine throughout the world, is the light of the fire wherewith he himself was enkindled. By the flames which he endured, he hath made hot every Christian heart.
+
+    Who is there but knoweth how that Lawrence chose rather to burn in earthly flames for a while, than to suffer the eternal fire of hell? The example, therefore, of blessed Lawrence provoketh us to lift up our testimony, kindleth our faith, and setteth our love all a-glow. If for us there are now no fires of persecution, the flame of faith is not therefore quenched. We give not our bodies to be burned for Christ's sake, but our hearts burn with His love. The persecutor stirreth up no fire around me, but a fire is stirred up in me by the longing for the presence of my Saviour.
+
+    But that the Saviour hath a fire of His own we read in the Gospel, where the Lord saith I am come to send fire on the earth, and what will I but that it be kindled? Luke xii. 49. It was this fire which had been enkindled in the two disciples when they said Did not our heart burn within us, while He talked with us by the way, and while He opened to us the Scriptures? Luke xxiv. 32. It was because this fire had been enkindled within him that the blessed Lawrence felt not the burning of the flames, and through eager yearning for the sight of Christ perceived not the cruelty of his persecutor.
