Close out P/T/S/N: St. Benedict's/All Saints Benedictine's own content, St. Michael redirect bug

The last 2 duplex-majus+ saints held back from the original 29-saint
P/T/S/N pass (for lacking a collect at the time) get the same
individual live-query treatment as their peers: real, unique proper
text for both (St. Benedict's own Prime antiphon is the opening line of
St. Gregory the Great's Life of St. Benedict; All Saints of the
Benedictine Order draws on Matt 13:43, Luke 6:22-23, and a well-known
All Saints antiphon) -- 14 new files, English translated throughout
since the source rendered none for either.

A final calendar-wide sweep (every saint's resolveMinorHourAntiphon/
resolveMinorHourChapter) turned up one more real gap, in the mechanism
itself rather than missing data: St. Michael's propers field points at
Apparition of St. Michael's own id (the two feasts are word-for-word
identical), and getDayCollect/getBenedictusAntiphon both explicitly
follow propers when resolving content -- but getMinorHourOverrideId
doesn't; it keys off the day's own winner id directly, so
resolveMinorHourAntiphon was looking for a file that could never exist.
Fixed the same way as Finding of St. Stephen: minorHoursCommon points
directly at his delegate's already-authored proper files.

Every real saint on this app's calendar now has real P/T/S/N content.
The only remaining absence is Ss. Ursula and Companions (no way to
verify a category of one) and the example-confessor test placeholder,
which was never meant to have any.
