Author Benedictus antiphon + P/T/S/N Commons for 66 propers:null saints

Continues the 94-saint batch this collects pass unblocked. Raw
Commune/*.txt fields don't reliably match what the engine actually
renders per hour -- same lesson as the collects pass, confirmed again:
no CommuneM/*.txt file defines explicit per-hour antiphon fields for any
category this batch needed, and the already-authored
common-of-a-confessor-bishop content (from the original 29-saint pass)
doesn't match Commune/C4.txt's own raw [Ant 1] either, since it was
live-query-sourced rather than read from the file directly. Fixed by
querying web/cgi-bin/horas/officium.pl directly (local Perl, not a
network fetch) for one representative saint per Common category, with
every representative's title verified against an accent-insensitive
name-stem match before its content is trusted -- caught a stale-date bug
this way: St. Emerentiana's stored clean-year comment actually rendered
St. Hilary of Poitiers's office that year.

Cross-querying multiple saints per nominal SaintRecord.common category
found the real liturgical groupings are coarser (Martyr-Bishop and
Martyr; Abbot, Confessor-not-Bishop, and Confessor; Virgin-Martyr,
Virgin, and Holy Woman all render identical minor-hour text) but not
uniformly so (Pope-Martyrs render distinct allelúja-toned text from
plain Several-Martyrs; the Dedication of the Basilicas of Ss. Peter and
Paul draws from the Dedication Common, not its nominal
common-of-an-apostle at all). Net: 7 new shared Common categories plus
the pre-existing common-of-a-confessor-bishop (which also needed a new
Benedictus-antiphon file of its own) cover 66 of the 94 saints.

New mechanism: SaintRecord.benedictusCommon, with getBenedictusAntiphon
falling back to it the same way getDayCollect already falls back to
collectCommon -- no name-substitution needed here, since every Common
category in current use renders name-free Benedictus-antiphon text.

Also fixes a real bug this surfaced: getMinorHourOverrideId gated all
Prime/Terce/Sext/None lookup behind the same duplex-majus+ threshold
Lauds' own psalmody override uses, on the assumption that only a strong
feast carries its own minor-hour content -- live-querying proved that
wrong (a winning Semiduplex saint still renders its own antiphons, not
the ferial default). Lauds' psalmody override itself stays majus+-gated
correctly, since it's a much bigger per-saint commitment this batch
doesn't add a Common fallback for.

Ss. Ursula and Companions deliberately left without a minor-hour Common:
her collect template has no other calendar member to verify a shared
text against, and she can never be queried directly (a genuinely
unwinnable stub) -- left honestly unauthored rather than guessed.

The other 26 of the 94 (own proper collect, from the collects batch)
still need their own individually-authored Benedictus antiphon, same
shape as the original 109-saint pass -- not done in this pass.
